-    * (red,green,blue,white)x(x,y).  This loses one degree of freedom and

-    * therefore an arbitrary ninth value has to be introduced to undo the

-    * original transformations.

-    *

-    * Think of the original end-points as points in (X,Y,Z) space.  The

-    * chromaticity values (c) have the property:

-    *

-    *           C

-    *   c = ---------

-    *       X + Y + Z

-    *

-    * For each c (x,y,z) from the corresponding original C (X,Y,Z).  Thus the

-    * three chromaticity values (x,y,z) for each end-point obey the

-    * relationship:

-    *

-    *   x + y + z = 1

-    *

-    * This describes the plane in (X,Y,Z) space that intersects each axis at the

-    * value 1.0; call this the chromaticity plane.  Thus the chromaticity

-    * calculation has scaled each end-point so that it is on the x+y+z=1 plane

-    * and chromaticity is the intersection of the vector from the origin to the

-    * (X,Y,Z) value with the chromaticity plane.

-    *

-    * To fully invert the chromaticity calculation we would need the three

-    * end-point scale factors, (red-scale, green-scale, blue-scale), but these

-    * were not recorded.  Instead we calculated the reference white (X,Y,Z) and

-    * recorded the chromaticity of this.  The reference white (X,Y,Z) would have

-    * given all three of the scale factors since:

-    *

-    *    color-C = color-c * color-scale

-    *    white-C = red-C + green-C + blue-C

-    *            = red-c*red-scale + green-c*green-scale + blue-c*blue-scale

-    *

-    * But cHRM records only white-x and white-y, so we have lost the white scale

-    * factor:

-    *

-    *    white-C = white-c*white-scale

-    *

-    * To handle this the inverse transformation makes an arbitrary assumption

-    * about white-scale:

-    *

-    *    Assume: white-Y = 1.0

-    *    Hence:  white-scale = 1/white-y

-    *    Or:     red-Y + green-Y + blue-Y = 1.0

-    *

-    * Notice the last statement of the assumption gives an equation in three of

-    * the nine values we want to calculate.  8 more equations come from the

-    * above routine as summarised at the top above (the chromaticity

-    * calculation):

-    *

-    *    Given: color-x = color-X / (color-X + color-Y + color-Z)

-    *    Hence: (color-x - 1)*color-X + color.x*color-Y + color.x*color-Z = 0

-    *

-    * This is 9 simultaneous equations in the 9 variables "color-C" and can be

-    * solved by Cramer's rule.  Cramer's rule requires calculating 10 9x9 matrix

-    * determinants, however this is not as bad as it seems because only 28 of

-    * the total of 90 terms in the various matrices are non-zero.  Nevertheless

-    * Cramer's rule is notoriously numerically unstable because the determinant

-    * calculation involves the difference of large, but similar, numbers.  It is

-    * difficult to be sure that the calculation is stable for real world values

-    * and it is certain that it becomes unstable where the end points are close

-    * together.

-    *

-    * So this code uses the perhaps slightly less optimal but more

-    * understandable and totally obvious approach of calculating color-scale.

-    *

-    * This algorithm depends on the precision in white-scale and that is

-    * (1/white-y), so we can immediately see that as white-y approaches 0 the

-    * accuracy inherent in the cHRM chunk drops off substantially.

-    *

-    * libpng arithmetic: a simple invertion of the above equations

-    * ------------------------------------------------------------

-    *

-    *    white_scale = 1/white-y

-    *    white-X = white-x * white-scale

-    *    white-Y = 1.0

-    *    white-Z = (1 - white-x - white-y) * white_scale

-    *

-    *    white-C = red-C + green-C + blue-C

-    *            = red-c*red-scale + green-c*green-scale + blue-c*blue-scale

-    *

-    * This gives us three equations in (red-scale,green-scale,blue-scale) where

-    * all the coefficients are now known:

-    *

-    *    red-x*red-scale + green-x*green-scale + blue-x*blue-scale

-    *       = white-x/white-y

-    *    red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1

-    *    red-z*red-scale + green-z*green-scale + blue-z*blue-scale

-    *       = (1 - white-x - white-y)/white-y

-    *

-    * In the last equation color-z is (1 - color-x - color-y) so we can add all

-    * three equations together to get an alternative third:

-    *

-    *    red-scale + green-scale + blue-scale = 1/white-y = white-scale

-    *

-    * So now we have a Cramer's rule solution where the determinants are just

-    * 3x3 - far more tractible.  Unfortunately 3x3 determinants still involve

-    * multiplication of three coefficients so we can't guarantee to avoid

-    * overflow in the libpng fixed point representation.  Using Cramer's rule in

-    * floating point is probably a good choice here, but it's not an option for

-    * fixed point.  Instead proceed to simplify the first two equations by

-    * eliminating what is likely to be the largest value, blue-scale:

-    *

-    *    blue-scale = white-scale - red-scale - green-scale

-    *

-    * Hence:

-    *

-    *    (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale =

-    *                (white-x - blue-x)*white-scale

-    *

-    *    (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale =

-    *                1 - blue-y*white-scale

-    *

-    * And now we can trivially solve for (red-scale,green-scale):

-    *

-    *    green-scale =

-    *                (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale

-    *                -----------------------------------------------------------

-    *                                  green-x - blue-x

-    *

-    *    red-scale =

-    *                1 - blue-y*white-scale - (green-y - blue-y) * green-scale

-    *                ---------------------------------------------------------

-    *                                  red-y - blue-y

-    *

-    * Hence:

-    *

-    *    red-scale =

-    *          ( (green-x - blue-x) * (white-y - blue-y) -

-    *            (green-y - blue-y) * (white-x - blue-x) ) / white-y

-    * -------------------------------------------------------------------------

-    *  (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)

-    *

-    *    green-scale =

-    *          ( (red-y - blue-y) * (white-x - blue-x) -

-    *            (red-x - blue-x) * (white-y - blue-y) ) / white-y

-    * -------------------------------------------------------------------------

-    *  (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)

-    *

-    * Accuracy:

-    * The input values have 5 decimal digits of accuracy.  The values are all in

-    * the range 0 < value < 1, so simple products are in the same range but may

-    * need up to 10 decimal digits to preserve the original precision and avoid

-    * underflow.  Because we are using a 32-bit signed representation we cannot

-    * match this; the best is a little over 9 decimal digits, less than 10.

-    *

-    * The approach used here is to preserve the maximum precision within the

-    * signed representation.  Because the red-scale calculation above uses the

-    * difference between two products of values that must be in the range -1..+1

-    * it is sufficient to divide the product by 7; ceil(100,000/32767*2).  The

-    * factor is irrelevant in the calculation because it is applied to both

-    * numerator and denominator.

-    *

-    * Note that the values of the differences of the products of the

-    * chromaticities in the above equations tend to be small, for example for

-    * the sRGB chromaticities they are:

-    *

-    * red numerator:    -0.04751

-    * green numerator:  -0.08788

-    * denominator:      -0.2241 (without white-y multiplication)

-    *

-    *  The resultant Y coefficients from the chromaticities of some widely used

-    *  color space definitions are (to 15 decimal places):

-    *

-    *  sRGB

+    * (red,green,blue,white)x(x,y).  This loses one degree of freedom and
+    * therefore an arbitrary ninth value has to be introduced to undo the
+    * original transformations.
+    *
+    * Think of the original end-points as points in (X,Y,Z) space.  The
+    * chromaticity values (c) have the property:
+    *
+    *           C
+    *   c = ---------
+    *       X + Y + Z
+    *
+    * For each c (x,y,z) from the corresponding original C (X,Y,Z).  Thus the
+    * three chromaticity values (x,y,z) for each end-point obey the
+    * relationship:
+    *
+    *   x + y + z = 1
+    *
+    * This describes the plane in (X,Y,Z) space that intersects each axis at the
+    * value 1.0; call this the chromaticity plane.  Thus the chromaticity
+    * calculation has scaled each end-point so that it is on the x+y+z=1 plane
+    * and chromaticity is the intersection of the vector from the origin to the
+    * (X,Y,Z) value with the chromaticity plane.
+    *
+    * To fully invert the chromaticity calculation we would need the three
+    * end-point scale factors, (red-scale, green-scale, blue-scale), but these
+    * were not recorded.  Instead we calculated the reference white (X,Y,Z) and
+    * recorded the chromaticity of this.  The reference white (X,Y,Z) would have
+    * given all three of the scale factors since:
+    *
+    *    color-C = color-c * color-scale
+    *    white-C = red-C + green-C + blue-C
+    *            = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+    *
+    * But cHRM records only white-x and white-y, so we have lost the white scale
+    * factor:
+    *
+    *    white-C = white-c*white-scale
+    *
+    * To handle this the inverse transformation makes an arbitrary assumption
+    * about white-scale:
+    *
+    *    Assume: white-Y = 1.0
+    *    Hence:  white-scale = 1/white-y
+    *    Or:     red-Y + green-Y + blue-Y = 1.0
+    *
+    * Notice the last statement of the assumption gives an equation in three of
+    * the nine values we want to calculate.  8 more equations come from the
+    * above routine as summarised at the top above (the chromaticity
+    * calculation):
+    *
+    *    Given: color-x = color-X / (color-X + color-Y + color-Z)
+    *    Hence: (color-x - 1)*color-X + color.x*color-Y + color.x*color-Z = 0
+    *
+    * This is 9 simultaneous equations in the 9 variables "color-C" and can be
+    * solved by Cramer's rule.  Cramer's rule requires calculating 10 9x9 matrix
+    * determinants, however this is not as bad as it seems because only 28 of
+    * the total of 90 terms in the various matrices are non-zero.  Nevertheless
+    * Cramer's rule is notoriously numerically unstable because the determinant
+    * calculation involves the difference of large, but similar, numbers.  It is
+    * difficult to be sure that the calculation is stable for real world values
+    * and it is certain that it becomes unstable where the end points are close
+    * together.
+    *
+    * So this code uses the perhaps slightly less optimal but more
+    * understandable and totally obvious approach of calculating color-scale.
+    *
+    * This algorithm depends on the precision in white-scale and that is
+    * (1/white-y), so we can immediately see that as white-y approaches 0 the
+    * accuracy inherent in the cHRM chunk drops off substantially.
+    *
+    * libpng arithmetic: a simple inversion of the above equations
+    * ------------------------------------------------------------
+    *
+    *    white_scale = 1/white-y
+    *    white-X = white-x * white-scale
+    *    white-Y = 1.0
+    *    white-Z = (1 - white-x - white-y) * white_scale
+    *
+    *    white-C = red-C + green-C + blue-C
+    *            = red-c*red-scale + green-c*green-scale + blue-c*blue-scale
+    *
+    * This gives us three equations in (red-scale,green-scale,blue-scale) where
+    * all the coefficients are now known:
+    *
+    *    red-x*red-scale + green-x*green-scale + blue-x*blue-scale
+    *       = white-x/white-y
+    *    red-y*red-scale + green-y*green-scale + blue-y*blue-scale = 1
+    *    red-z*red-scale + green-z*green-scale + blue-z*blue-scale
+    *       = (1 - white-x - white-y)/white-y
+    *
+    * In the last equation color-z is (1 - color-x - color-y) so we can add all
+    * three equations together to get an alternative third:
+    *
+    *    red-scale + green-scale + blue-scale = 1/white-y = white-scale
+    *
+    * So now we have a Cramer's rule solution where the determinants are just
+    * 3x3 - far more tractible.  Unfortunately 3x3 determinants still involve
+    * multiplication of three coefficients so we can't guarantee to avoid
+    * overflow in the libpng fixed point representation.  Using Cramer's rule in
+    * floating point is probably a good choice here, but it's not an option for
+    * fixed point.  Instead proceed to simplify the first two equations by
+    * eliminating what is likely to be the largest value, blue-scale:
+    *
+    *    blue-scale = white-scale - red-scale - green-scale
+    *
+    * Hence:
+    *
+    *    (red-x - blue-x)*red-scale + (green-x - blue-x)*green-scale =
+    *                (white-x - blue-x)*white-scale
+    *
+    *    (red-y - blue-y)*red-scale + (green-y - blue-y)*green-scale =
+    *                1 - blue-y*white-scale
+    *
+    * And now we can trivially solve for (red-scale,green-scale):
+    *
+    *    green-scale =
+    *                (white-x - blue-x)*white-scale - (red-x - blue-x)*red-scale
+    *                -----------------------------------------------------------
+    *                                  green-x - blue-x
+    *
+    *    red-scale =
+    *                1 - blue-y*white-scale - (green-y - blue-y) * green-scale
+    *                ---------------------------------------------------------
+    *                                  red-y - blue-y
+    *
+    * Hence:
+    *
+    *    red-scale =
+    *          ( (green-x - blue-x) * (white-y - blue-y) -
+    *            (green-y - blue-y) * (white-x - blue-x) ) / white-y
+    * -------------------------------------------------------------------------
+    *  (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+    *
+    *    green-scale =
+    *          ( (red-y - blue-y) * (white-x - blue-x) -
+    *            (red-x - blue-x) * (white-y - blue-y) ) / white-y
+    * -------------------------------------------------------------------------
+    *  (green-x - blue-x)*(red-y - blue-y)-(green-y - blue-y)*(red-x - blue-x)
+    *
+    * Accuracy:
+    * The input values have 5 decimal digits of accuracy.  The values are all in
+    * the range 0 < value < 1, so simple products are in the same range but may
+    * need up to 10 decimal digits to preserve the original precision and avoid
+    * underflow.  Because we are using a 32-bit signed representation we cannot
+    * match this; the best is a little over 9 decimal digits, less than 10.
+    *
+    * The approach used here is to preserve the maximum precision within the
+    * signed representation.  Because the red-scale calculation above uses the
+    * difference between two products of values that must be in the range -1..+1
+    * it is sufficient to divide the product by 7; ceil(100,000/32767*2).  The
+    * factor is irrelevant in the calculation because it is applied to both
+    * numerator and denominator.
+    *
+    * Note that the values of the differences of the products of the
+    * chromaticities in the above equations tend to be small, for example for
+    * the sRGB chromaticities they are:
+    *
+    * red numerator:    -0.04751
+    * green numerator:  -0.08788
+    * denominator:      -0.2241 (without white-y multiplication)
+    *
+    *  The resultant Y coefficients from the chromaticities of some widely used
+    *  color space definitions are (to 15 decimal places):
+    *
+    *  sRGB

- * Note about libpng version numbers:
- *
- *   Due to various miscommunications, unforeseen code incompatibilities
- *   and occasional factors outside the authors' control, version numbering
- *   on the library has not always been consistent and straightforward.
- *   The following table summarizes matters since version 0.89c, which was
- *   the first widely used release:

  *
  * The alternative is to 'associate' the alpha with the color information by
- * storing color channel values that have been scaled by the alpha.  The
- * advantage is that the color channels can be resampled (the image can be
- * scaled) in this form.  The disadvantage is that normal practice is to store
- * linear, not (gamma) encoded, values and this requires 16-bit channels for

 /* The output_gamma value is a screen gamma in libpng terminology: it expresses

- * sRGB.)
- *
- * The inverse of the value is always used to provide a default for the PNG file
- * encoding if it has no gAMA chunk and if png_set_gamma() has not been called
- * to override the PNG gamma information.
- *
- * When the ALPHA_OPTIMIZED mode is selected the output gamma is used to encode
- * opaque pixels however pixels with lower alpha values are not encoded,
- * regardless of the output gamma setting.
- *
- * When the standard Porter Duff handling is requested with mode 1 the output
- * encoding is set to be linear and the output_gamma value is only relevant
- * as a default for input data that has no gamma information.  The linear output
- * encoding will be overridden if png_set_gamma() is called - the results may be
- * highly unexpected!
- *
- * The following numbers are derived from the sRGB standard and the research
- * behind it.  sRGB is defined to be approximated by a PNG gAMA chunk value of
- * 0.45455 (1/2.2) for PNG.  The value implicitly includes any viewing
- * correction required to take account of any differences in the color
- * environment of the original scene and the intended display environment; the
- * value expresses how to *decode* the image for display, not how the original
- * data was *encoded*.
- *
- * sRGB provides a peg for the PNG standard by defining a viewing environment.
- * sRGB itself, and earlier TV standards, actually use a more complex transform
- * (a linear portion then a gamma 2.4 power law) than PNG can express.  (PNG is
- * limited to simple power laws.)  By saying that an image for direct display on
- * an sRGB conformant system should be stored with a gAMA chunk value of 45455
- * (11.3.3.2 and 11.3.3.5 of the ISO PNG specification) the PNG specification
- * makes it possible to derive values for other display systems and
- * environments.
- *
- * The Mac value is deduced from the sRGB based on an assumption that the actual
- * extra viewing correction used in early Mac display systems was implemented as
- * a power 1.45 lookup table.
- *
- * Any system where a programmable lookup table is used or where the behavior of
- * the final display device characteristics can be changed requires system
- * specific code to obtain the current characteristic.  However this can be
- * difficult and most PNG gamma correction only requires an approximate value.
- *
- * By default, if png_set_alpha_mode() is not called, libpng assumes that all
- * values are unencoded, linear, values and that the output device also has a
- * linear characteristic.  This is only very rarely correct - it is invariably
- * better to call png_set_alpha_mode() with PNG_DEFAULT_sRGB than rely on the
- * default if you don't know what the right answer is!
- *
- * The special value PNG_GAMMA_MAC_18 indicates an older Mac system (pre Mac OS
- * 10.6) which used a correction table to implement a somewhat lower gamma on an
- * otherwise sRGB system.
- *
- * Both these values are reserved (not simple gamma values) in order to allow
- * more precise correction internally in the future.

- * Weights are factors >= 1.0, indicating how important it is to keep the

- * filter is that many times as likely to be the same as the "num_weights"
- * previous filters.  This is cumulative for each previous row with a weight.
- * There needs to be "num_weights" values in "filter_weights", or it can be
- * NULL if the weights aren't being specified.  Weights have no influence on
- * the selection of the first row filter.  Well chosen weights can (in theory)
- * improve the compression for a given image.
- *
- * Costs are factors >= 1.0 indicating the relative decoding costs of a
- * filter type.  Higher costs indicate more decoding expense, and are
- * therefore less likely to be selected over a filter with lower computational
- * costs.  There needs to be a value in "filter_costs" for each valid filter
- * type (given by PNG_FILTER_VALUE_LAST), or it can be NULL if you aren't
- * setting the costs.  Costs try to improve the speed of decompression without
- * unduly increasing the compressed image size.
- *
- * A negative weight or cost indicates the default value is to be used, and
- * values in the range [0.0, 1.0) indicate the value is to remain unchanged.
- * The default values for both weights and costs are currently 1.0, but may
- * change if good general weighting/cost heuristics can be found.  If both
- * the weights and costs are set to 1.0, this degenerates the WEIGHTED method
- * to the UNWEIGHTED method, but with added encoding time/computation.

-/* Function calling conventions.

- * =============================

- * Normally it is not necessary to specify to the compiler how to call

- * a function - it just does it - however on x86 systems derived from

- * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems

- * and some others) there are multiple ways to call a function and the

- * default can be changed on the compiler command line.  For this reason

- * libpng specifies the calling convention of every exported function and

- * every function called via a user supplied function pointer.  This is

- * done in this file by defining the following macros:

- *

- * PNGAPI    Calling convention for exported functions.

- * PNGCBAPI  Calling convention for user provided (callback) functions.

- * PNGCAPI   Calling convention used by the ANSI-C library (required

- *           for longjmp callbacks and sometimes used internally to

- *           specify the calling convention for zlib).

- *

- * These macros should never be overridden.  If it is necessary to

- * change calling convention in a private build this can be done

- * by setting PNG_API_RULE (which defaults to 0) to one of the values

- * below to select the correct 'API' variants.

- *

- * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.

- *                This is correct in every known environment.

- * PNG_API_RULE=1 Use the operating system convention for PNGAPI and

- *                the 'C' calling convention (from PNGCAPI) for

- *                callbacks (PNGCBAPI).  This is no longer required

- *                in any known environment - if it has to be used

- *                please post an explanation of the problem to the

- *                libpng mailing list.

- *

- * These cases only differ if the operating system does not use the C

- * calling convention, at present this just means the above cases

- * (x86 DOS/Windows sytems) and, even then, this does not apply to

- * Cygwin running on those systems.

- *

- * Note that the value must be defined in pnglibconf.h so that what

- * the application uses to call the library matches the conventions

- * set when building the library.

- */

-

-/* Symbol export

- * =============

- * When building a shared library it is almost always necessary to tell

- * the compiler which symbols to export.  The png.h macro 'PNG_EXPORT'

- * is used to mark the symbols.  On some systems these symbols can be

- * extracted at link time and need no special processing by the compiler,

- * on other systems the symbols are flagged by the compiler and just

- * the declaration requires a special tag applied (unfortunately) in a

- * compiler dependent way.  Some systems can do either.

- *

- * A small number of older systems also require a symbol from a DLL to

- * be flagged to the program that calls it.  This is a problem because

- * we do not know in the header file included by application code that

- * the symbol will come from a shared library, as opposed to a statically

- * linked one.  For this reason the application must tell us by setting

- * the magic flag PNG_USE_DLL to turn on the special processing before

- * it includes png.h.

- *

- * Four additional macros are used to make this happen:

- *

- * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from

- *            the build or imported if PNG_USE_DLL is set - compiler

- *            and system specific.

- *

- * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to

- *                       'type', compiler specific.

- *

- * PNG_DLL_EXPORT Set to the magic to use during a libpng build to

- *                make a symbol exported from the DLL.  Not used in the

- *                public header files; see pngpriv.h for how it is used

- *                in the libpng build.

- *

- * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come

- *                from a DLL - used to define PNG_IMPEXP when

- *                PNG_USE_DLL is set.

- */

-/* System specific discovery.

- * ==========================

- * This code is used at build time to find PNG_IMPEXP, the API settings

- * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL

- * import processing is possible.  On Windows systems it also sets

- * compiler-specific macros to the values required to change the calling

+/* Function calling conventions.
+ * =============================
+ * Normally it is not necessary to specify to the compiler how to call
+ * a function - it just does it - however on x86 systems derived from
+ * Microsoft and Borland C compilers ('IBM PC', 'DOS', 'Windows' systems
+ * and some others) there are multiple ways to call a function and the
+ * default can be changed on the compiler command line.  For this reason
+ * libpng specifies the calling convention of every exported function and
+ * every function called via a user supplied function pointer.  This is
+ * done in this file by defining the following macros:
+ *
+ * PNGAPI    Calling convention for exported functions.
+ * PNGCBAPI  Calling convention for user provided (callback) functions.
+ * PNGCAPI   Calling convention used by the ANSI-C library (required
+ *           for longjmp callbacks and sometimes used internally to
+ *           specify the calling convention for zlib).
+ *
+ * These macros should never be overridden.  If it is necessary to
+ * change calling convention in a private build this can be done
+ * by setting PNG_API_RULE (which defaults to 0) to one of the values
+ * below to select the correct 'API' variants.
+ *
+ * PNG_API_RULE=0 Use PNGCAPI - the 'C' calling convention - throughout.
+ *                This is correct in every known environment.
+ * PNG_API_RULE=1 Use the operating system convention for PNGAPI and
+ *                the 'C' calling convention (from PNGCAPI) for
+ *                callbacks (PNGCBAPI).  This is no longer required
+ *                in any known environment - if it has to be used
+ *                please post an explanation of the problem to the
+ *                libpng mailing list.
+ *
+ * These cases only differ if the operating system does not use the C
+ * calling convention, at present this just means the above cases
+ * (x86 DOS/Windows sytems) and, even then, this does not apply to
+ * Cygwin running on those systems.
+ *
+ * Note that the value must be defined in pnglibconf.h so that what
+ * the application uses to call the library matches the conventions
+ * set when building the library.
+ */
+
+/* Symbol export
+ * =============
+ * When building a shared library it is almost always necessary to tell
+ * the compiler which symbols to export.  The png.h macro 'PNG_EXPORT'
+ * is used to mark the symbols.  On some systems these symbols can be
+ * extracted at link time and need no special processing by the compiler,
+ * on other systems the symbols are flagged by the compiler and just
+ * the declaration requires a special tag applied (unfortunately) in a
+ * compiler dependent way.  Some systems can do either.
+ *
+ * A small number of older systems also require a symbol from a DLL to
+ * be flagged to the program that calls it.  This is a problem because
+ * we do not know in the header file included by application code that
+ * the symbol will come from a shared library, as opposed to a statically
+ * linked one.  For this reason the application must tell us by setting
+ * the magic flag PNG_USE_DLL to turn on the special processing before
+ * it includes png.h.
+ *
+ * Four additional macros are used to make this happen:
+ *
+ * PNG_IMPEXP The magic (if any) to cause a symbol to be exported from
+ *            the build or imported if PNG_USE_DLL is set - compiler
+ *            and system specific.
+ *
+ * PNG_EXPORT_TYPE(type) A macro that pre or appends PNG_IMPEXP to
+ *                       'type', compiler specific.
+ *
+ * PNG_DLL_EXPORT Set to the magic to use during a libpng build to
+ *                make a symbol exported from the DLL.  Not used in the
+ *                public header files; see pngpriv.h for how it is used
+ *                in the libpng build.
+ *
+ * PNG_DLL_IMPORT Set to the magic to force the libpng symbols to come
+ *                from a DLL - used to define PNG_IMPEXP when
+ *                PNG_USE_DLL is set.
+ */
+
+/* System specific discovery.
+ * ==========================
+ * This code is used at build time to find PNG_IMPEXP, the API settings
+ * and PNG_EXPORT_TYPE(), it may also set a macro to indicate the DLL
+ * import processing is possible.  On Windows systems it also sets
+ * compiler-specific macros to the values required to change the calling

- /* png_info is a structure that holds the information in a PNG file so

- * that the application can find out the characteristics of the image.

- * If you are reading the file, this structure will tell you what is

- * in the PNG file.  If you are writing the file, fill in the information

- * you want to put into the PNG file, using png_set_*() functions, then

- * call png_write_info().

- *

- * The names chosen should be very close to the PNG specification, so

- * consult that document for information about the meaning of each field.

- *

- * With libpng < 0.95, it was only possible to directly set and read the

- * the values in the png_info_struct, which meant that the contents and

- * order of the values had to remain fixed.  With libpng 0.95 and later,

- * however, there are now functions that abstract the contents of

- * png_info_struct from the application, so this makes it easier to use

- * libpng with dynamic libraries, and even makes it possible to use

- * libraries that don't have all of the libpng ancillary chunk-handing

- * functionality.  In libpng-1.5.0 this was moved into a separate private

- * file that is not visible to applications.

- *

- * The following members may have allocated storage attached that should be

- * cleaned up before the structure is discarded: palette, trans, text,

- * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,

- * splt_palettes, scal_unit, row_pointers, and unknowns.   By default, these

- * are automatically freed when the info structure is deallocated, if they were

- * allocated internally by libpng.  This behavior can be changed by means

- * of the png_data_freer() function.

- *

- * More allocation details: all the chunk-reading functions that

- * change these members go through the corresponding png_set_*

- * functions.  A function to clear these members is available: see

- * png_free_data().  The png_set_* functions do not depend on being

- * able to point info structure members to any of the storage they are

- * passed (they make their own copies), EXCEPT that the png_set_text

- * functions use the same storage passed to them in the text_ptr or

- * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns

- * functions do not make their own copies.

+ /* png_info is a structure that holds the information in a PNG file so
+ * that the application can find out the characteristics of the image.
+ * If you are reading the file, this structure will tell you what is
+ * in the PNG file.  If you are writing the file, fill in the information
+ * you want to put into the PNG file, using png_set_*() functions, then
+ * call png_write_info().
+ *
+ * The names chosen should be very close to the PNG specification, so
+ * consult that document for information about the meaning of each field.
+ *
+ * With libpng < 0.95, it was only possible to directly set and read the
+ * the values in the png_info_struct, which meant that the contents and
+ * order of the values had to remain fixed.  With libpng 0.95 and later,
+ * however, there are now functions that abstract the contents of
+ * png_info_struct from the application, so this makes it easier to use
+ * libpng with dynamic libraries, and even makes it possible to use
+ * libraries that don't have all of the libpng ancillary chunk-handing
+ * functionality.  In libpng-1.5.0 this was moved into a separate private
+ * file that is not visible to applications.
+ *
+ * The following members may have allocated storage attached that should be
+ * cleaned up before the structure is discarded: palette, trans, text,
+ * pcal_purpose, pcal_units, pcal_params, hist, iccp_name, iccp_profile,
+ * splt_palettes, scal_unit, row_pointers, and unknowns.   By default, these
+ * are automatically freed when the info structure is deallocated, if they were
+ * allocated internally by libpng.  This behavior can be changed by means
+ * of the png_data_freer() function.
+ *
+ * More allocation details: all the chunk-reading functions that
+ * change these members go through the corresponding png_set_*
+ * functions.  A function to clear these members is available: see
+ * png_free_data().  The png_set_* functions do not depend on being
+ * able to point info structure members to any of the storage they are
+ * passed (they make their own copies), EXCEPT that the png_set_text
+ * functions use the same storage passed to them in the text_ptr or
+ * itxt_ptr structure argument, and the png_set_rows and png_set_unknowns
+ * functions do not make their own copies.

- * =====================

- * When this happens configure-time setting of the target host options cannot be

- * done and this interferes with the handling of the ARM NEON optimizations, and

- * possibly other similar optimizations.  Put additional tests here; in general

- * this is needed when the same option can be changed at both compile time and

- * run time depending on the target OS (i.e. iOS vs Android.)

- *

- * NOTE: symbol prefixing does not pass $(CFLAGS) to the preprocessor, because

- * this is not possible with certain compilers (Oracle SUN OS CC), as a result

- * it is necessary to ensure that all extern functions that *might* be used

- * regardless of $(CFLAGS) get declared in this file.  The test on __ARM_NEON__

- * below is one example of this behavior because it is controlled by the

- * presence or not of -mfpu=neon on the GCC command line, it is possible to do

- * this in $(CC), e.g. "CC=gcc -mfpu=neon", but people who build libpng rarely

- * do this.

-/* From Andreas Dilger e-mail to png-implement, 26 March 1998:

- *

- *   In most cases, the "simple transparency" should be done prior to doing

- *   gray-to-RGB, or you will have to test 3x as many bytes to check if a

- *   pixel is transparent.  You would also need to make sure that the

- *   transparency information is upgraded to RGB.

- *

- *   To summarize, the current flow is:

- *   - Gray + simple transparency -> compare 1 or 2 gray bytes and composite

- *                                   with background "in place" if transparent,

- *                                   convert to RGB if necessary

- *   - Gray + alpha -> composite with gray background and remove alpha bytes,

- *                                   convert to RGB if necessary

- *

- *   To support RGB backgrounds for gray images we need:

- *   - Gray + simple transparency -> convert to RGB + simple transparency,

- *                                   compare 3 or 6 bytes and composite with

- *                                   background "in place" if transparent

- *                                   (3x compare/pixel compared to doing

- *                                   composite with gray bkgrnd)

- *   - Gray + alpha -> convert to RGB + alpha, composite with background and

- *                                   remove alpha bytes (3x float

- *                                   operations/pixel compared with composite

- *                                   on gray background)

- *

- *  Greg's change will do this.  The reason it wasn't done before is for

- *  performance, as this increases the per-pixel operations.  If we would check

- *  in advance if the background was gray or RGB, and position the gray-to-RGB

- *  transform appropriately, then it would save a lot of work/time.

- *     Y = (6969 * R + 23434 * G + 2365 * B)/32768

- *

- * Poynton's current link (as of January 2003 through July 2011):

- * <http://www.poynton.com/notes/colour_and_gamma/>

- * has changed the numbers slightly:

- *

- *     Y = 0.2126*R + 0.7152*G + 0.0722*B

- *

- *  which can be expressed with integers as

- *

- *     Y = (6966 * R + 23436 * G + 2366 * B)/32768

- *

- *  Historically, however, libpng uses numbers derived from the ITU-R Rec 709

- *  end point chromaticities and the D65 white point.  Depending on the

- *  precision used for the D65 white point this produces a variety of different

- *  numbers, however if the four decimal place value used in ITU-R Rec 709 is

- *  used (0.3127,0.3290) the Y calculation would be:

- *

- *     Y = (6968 * R + 23435 * G + 2366 * B)/32768

- *

- *  While this is correct the rounding results in an overflow for white, because

- *  the sum of the rounded coefficients is 32769, not 32768.  Consequently

- *  libpng uses, instead, the closest non-overflowing approximation:

- *

- *     Y = (6968 * R + 23434 * G + 2366 * B)/32768

- *

- *  Starting with libpng-1.5.5, if the image being converted has a cHRM chunk

- *  (including an sRGB chunk) then the chromaticities are used to calculate the

- *  coefficients.  See the chunk handling in pngrutil.c for more information.

- *

- *  In all cases the calculation is to be done in a linear colorspace.  If no

- *  gamma information is available to correct the encoding of the original RGB

- *  values this results in an implicit assumption that the original PNG RGB

- *  values were linear.

- *

- *  Other integer coefficents can be used via png_set_rgb_to_gray().  Because

- *  the API takes just red and green coefficients the blue coefficient is

- *  calculated to make the sum 32768.  This will result in different rounding

- *  to that used above.

+ * Poynton's current link (as of January 2003 through July 2011):
+ * <http://www.poynton.com/notes/colour_and_gamma/>
+ * has changed the numbers slightly:
+ *
+ *     Y = 0.2126*R + 0.7152*G + 0.0722*B
+ *
+ *  which can be expressed with integers as
+ *
+ *     Y = (6966 * R + 23436 * G + 2366 * B)/32768
+ *
+ *  Historically, however, libpng uses numbers derived from the ITU-R Rec 709
+ *  end point chromaticities and the D65 white point.  Depending on the
+ *  precision used for the D65 white point this produces a variety of different
+ *  numbers, however if the four decimal place value used in ITU-R Rec 709 is
+ *  used (0.3127,0.3290) the Y calculation would be:
+ *
+ *     Y = (6968 * R + 23435 * G + 2366 * B)/32768
+ *
+ *  While this is correct the rounding results in an overflow for white, because
+ *  the sum of the rounded coefficients is 32769, not 32768.  Consequently
+ *  libpng uses, instead, the closest non-overflowing approximation:
+ *
+ *     Y = (6968 * R + 23434 * G + 2366 * B)/32768
+ *
+ *  Starting with libpng-1.5.5, if the image being converted has a cHRM chunk
+ *  (including an sRGB chunk) then the chromaticities are used to calculate the
+ *  coefficients.  See the chunk handling in pngrutil.c for more information.
+ *
+ *  In all cases the calculation is to be done in a linear colorspace.  If no
+ *  gamma information is available to correct the encoding of the original RGB
+ *  values this results in an implicit assumption that the original PNG RGB
+ *  values were linear.
+ *
+ *  Other integer coefficents can be used via png_set_rgb_to_gray().  Because
+ *  the API takes just red and green coefficients the blue coefficient is
+ *  calculated to make the sum 32768.  This will result in different rounding
+ *  to that used above.

+/* From Andreas Dilger e-mail to png-implement, 26 March 1998:
+ *
+ *   In most cases, the "simple transparency" should be done prior to doing
+ *   gray-to-RGB, or you will have to test 3x as many bytes to check if a
+ *   pixel is transparent.  You would also need to make sure that the
+ *   transparency information is upgraded to RGB.
+ *
+ *   To summarize, the current flow is:
+ *   - Gray + simple transparency -> compare 1 or 2 gray bytes and composite
+ *                                   with background "in place" if transparent,
+ *                                   convert to RGB if necessary
+ *   - Gray + alpha -> composite with gray background and remove alpha bytes,
+ *                                   convert to RGB if necessary
+ *
+ *   To support RGB backgrounds for gray images we need:
+ *   - Gray + simple transparency -> convert to RGB + simple transparency,
+ *                                   compare 3 or 6 bytes and composite with
+ *                                   background "in place" if transparent
+ *                                   (3x compare/pixel compared to doing
+ *                                   composite with gray bkgrnd)
+ *   - Gray + alpha -> convert to RGB + alpha, composite with background and

+
+/*
+ * TIFF Library.
+ * LogLuv compression support for high dynamic range images.
+ *
+ * Contributed by Greg Larson.
+ *
+ * LogLuv image support uses the TIFF library to store 16 or 10-bit
+ * log luminance values with 8 bits each of u and v or a 14-bit index.
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit integer values.  A 16-bit luminance is interpreted
+ * as a sign bit followed by a 15-bit integer that is converted
+ * to and from a linear magnitude using the transformation:
+ *
+ *	L = 2^( (Le+.5)/256 - 64 )		# real from 15-bit
+ *
+ *	Le = floor( 256*(log2(L) + 64) )	# 15-bit from real
+ *
+ * The actual conversion to world luminance units in candelas per sq. meter
+ * requires an additional multiplier, which is stored in the TIFFTAG_STONITS.
+ * This value is usually set such that a reasonable exposure comes from
+ * clamping decoded luminances above 1 to 1 in the displayed image.
+ *
+ * The 16-bit values for u and v may be converted to real values by dividing
+ * each by 32768.  (This allows for negative values, which aren't useful as
+ * far as we know, but are left in case of future improvements in human
+ * color vision.)
+ *
+ * Conversion from (u,v), which is actually the CIE (u',v') system for
+ * you color scientists, is accomplished by the following transformation:
+ *
+ *	u = 4*x / (-2*x + 12*y + 3)
+ *	v = 9*y / (-2*x + 12*y + 3)
+ *
+ *	x = 9*u / (6*u - 16*v + 12)
+ *	y = 4*v / (6*u - 16*v + 12)
+ *
+ * This process is greatly simplified by passing 32-bit IEEE floats
+ * for each of three CIE XYZ coordinates.  The codec then takes care
+ * of conversion to and from LogLuv, though the application is still
+ * responsible for interpreting the TIFFTAG_STONITS calibration factor.
+ *
+ * By definition, a CIE XYZ vector of [1 1 1] corresponds to a neutral white
+ * point of (x,y)=(1/3,1/3).  However, most color systems assume some other
+ * white point, such as D65, and an absolute color conversion to XYZ then
+ * to another color space with a different white point may introduce an
+ * unwanted color cast to the image.  It is often desirable, therefore, to
+ * perform a white point conversion that maps the input white to [1 1 1]
+ * in XYZ, then record the original white point using the TIFFTAG_WHITEPOINT
+ * tag value.  A decoder that demands absolute color calibration may use
+ * this white point tag to get back the original colors, but usually it
+ * will be ignored and the new white point will be used instead that
+ * matches the output color space.
+ *
+ * Pixel information is compressed into one of two basic encodings, depending
+ * on the setting of the compression tag, which is one of COMPRESSION_SGILOG
+ * or COMPRESSION_SGILOG24.  For COMPRESSION_SGILOG, greyscale data is
+ * stored as:
+ *
+ *	 1       15
+ *	|-+---------------|
+ *
+ * COMPRESSION_SGILOG color data is stored as:
+ *
+ *	 1       15           8        8
+ *	|-+---------------|--------+--------|
+ *	 S       Le           ue       ve
+ *
+ * For the 24-bit COMPRESSION_SGILOG24 color format, the data is stored as:
+ *
+ *	     10           14
+ *	|----------|--------------|
+ *	     Le'          Ce
+ *
+ * There is no sign bit in the 24-bit case, and the (u,v) chromaticity is
+ * encoded as an index for optimal color resolution.  The 10 log bits are
+ * defined by the following conversions:
+ *
+ *	L = 2^((Le'+.5)/64 - 12)		# real from 10-bit
+ *
+ *	Le' = floor( 64*(log2(L) + 12) )	# 10-bit from real
+ *
+ * The 10 bits of the smaller format may be converted into the 15 bits of
+ * the larger format by multiplying by 4 and adding 13314.  Obviously,
+ * a smaller range of magnitudes is covered (about 5 orders of magnitude
+ * instead of 38), and the lack of a sign bit means that negative luminances
+ * are not allowed.  (Well, they aren't allowed in the real world, either,
+ * but they are useful for certain types of image processing.)
+ *
+ * The desired user format is controlled by the setting the internal
+ * pseudo tag TIFFTAG_SGILOGDATAFMT to one of:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float XYZ values
+ *  SGILOGDATAFMT_16BIT	      = 16-bit integer encodings of logL, u and v
+ * Raw data i/o is also possible using:
+ *  SGILOGDATAFMT_RAW         = 32-bit unsigned integer with encoded pixel
+ * In addition, the following decoding is provided for ease of display:
+ *  SGILOGDATAFMT_8BIT        = 8-bit default RGB gamma-corrected values
+ *
+ * For grayscale images, we provide the following data formats:
+ *  SGILOGDATAFMT_FLOAT       = IEEE 32-bit float Y values
+ *  SGILOGDATAFMT_16BIT       = 16-bit integer w/ encoded luminance
+ *  SGILOGDATAFMT_8BIT        = 8-bit gray monitor values
+ *
+ * Note that the COMPRESSION_SGILOG applies a simple run-length encoding
+ * scheme by separating the logL, u and v bytes for each row and applying
+ * a PackBits type of compression.  Since the 24-bit encoding is not
+ * adaptive, the 32-bit color format takes less space in many cases.
+ *
+ * Further control is provided over the conversion from higher-resolution
+ * formats to final encoded values through the pseudo tag
+ * TIFFTAG_SGILOGENCODE:
+ *  SGILOGENCODE_NODITHER     = do not dither encoded values
+ *  SGILOGENCODE_RANDITHER    = apply random dithering during encoding
+ *
+ * The default value of this tag is SGILOGENCODE_NODITHER for
+ * COMPRESSION_SGILOG to maximize run-length encoding and
+ * SGILOGENCODE_RANDITHER for COMPRESSION_SGILOG24 to turn
+ * quantization errors into noise.

+/* What is what, and what is not?
+
+   This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
+   stream, if any, followed by the strile data, if any. This stream is read in
+   OJPEGReadByte and related functions.
+
+   It analyzes the start of this stream, until it encounters non-marker data, i.e.
+   compressed image data. Some of the header markers it sees have no actual content,
+   like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
+   other markers do have content, and the valuable bits and pieces of information
+   in these markers are saved, checking all to verify that the stream is more or
+   less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
+   functions.
+
+   Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
+   up on if we've seen no SOF marker when we're at the start of the compressed image
+   data. In this case, the tables are read from JpegXxxTables tags, and the other
+   bits and pieces of information is initialized to its most basic value. This is
+   implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
+
+   When this is complete, a good and valid JPEG header can be assembled, and this is
+   passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
+   the compressed image data, can be passed through unchanged. This is done in
+   OJPEGWriteStream functions.
+
+   LibTiff rightly expects to know the subsampling values before decompression. Just like
+   in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
+   tag is notoriously unreliable. To correct these tag values with the ones inside
+   the JPEG stream, the first part of the input stream is pre-scanned in
+   OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
+   or errors, up to the point where either these values are read, or it's clear they
+   aren't there. This means that some of the data is read twice, but we feel speed
+   in correcting these values is important enough to warrant this sacrifice. Allthough
+   there is currently no define or other configuration mechanism to disable this behaviour,
+   the actual header scanning is build to robustly respond with error report if it
+   should encounter an uncorrected mismatch of subsampling values. See
+   OJPEGReadHeaderInfoSecStreamSof.
+
+   The restart interval and restart markers are the most tricky part... The restart
+   interval can be specified in a tag. It can also be set inside the input JPEG stream.
+   It can be used inside the input JPEG stream. If reading from strile data, we've
+   consistenly discovered the need to insert restart markers in between the different
+   striles, as is also probably the most likely interpretation of the original TIFF 6.0
+   specification. With all this setting of interval, and actual use of markers that is not
+   predictable at the time of valid JPEG header assembly, the restart thing may turn
+   out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
+   succeed in reading back what they write, which may be the reason why we've been able
+   to discover ways that seem to work.
+
+   Some special provision is made for planarconfig separate OJPEG files. These seem
+   to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
+   and plane. This may or may not be a valid JPEG configuration, we don't know and don't
+   care. We want LibTiff to be able to access the planes individually, without huge
+   buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
+   case, that allow us to pass a single plane such that LibJpeg sees a valid
+   single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
+   planes, is done inside OJPEGReadSecondarySos.
+
+   The benefit of the scheme is... that it works, basically. We know of no other that
+   does. It works without checking software tag, or otherwise going about things in an
+   OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
+   with and without JpegInterchangeFormat, with and without striles, with part of
+   the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
+   and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
+   of the data.
+
+   Another nice side-effect is that a complete JPEG single valid stream is build if
+   planarconfig is not separate (vast majority). We may one day use that to build
+   converters to JPEG, and/or to new-style JPEG compression inside TIFF.
+
+   A dissadvantage is the lack of random access to the individual striles. This is the
+   reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
+   Applications would do well accessing all striles in order, as this will result in
+   a single sequential scan of the input stream, and no restarting of LibJpeg decoding
+   session.

+/* Configuration defines here are:
+ * JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump. In some environments,
+ * 	like eg LibTiffDelphi, this is not possible. For this reason, the actual calls to
+ * 	libjpeg, with longjump stuff, are encapsulated in dedicated functions. When
+ * 	JPEG_ENCAP_EXTERNAL is defined, these encapsulating functions are declared external
+ * 	to this unit, and can be defined elsewhere to use stuff other then longjump.
+ * 	The default mode, without JPEG_ENCAP_EXTERNAL, implements the call encapsulators
+ * 	here, internally, with normal longjump.
+ * SETJMP, LONGJMP, JMP_BUF: On some machines/environments a longjump equivalent is
+ * 	conviniently available, but still it may be worthwhile to use _setjmp or sigsetjmp
+ * 	in place of plain setjmp. These macros will make it easier. It is useless
+ * 	to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
+ * OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
+ * 	instant processing, optimal streaming and optimal use of processor cache, but also big
+ * 	enough so as to not result in significant call overhead. It should be at least a few
+ * 	bytes to accommodate some structures (this is verified in asserts), but it would not be
+ * 	sensible to make it this small anyway, and it should be at most 64K since it is indexed
+ * 	with uint16. We recommend 2K.
+ * EGYPTIANWALK: You could also define EGYPTIANWALK here, but it is not used anywhere and has
+ * 	absolutely no effect. That is why most people insist the EGYPTIANWALK is a bit silly.

+	 * TIFF but only supports some braindead idea of what the
+	 * vendor thinks TIFF is):
+	 *
+	 * 'l' use little-endian byte order for creating a file
+	 * 'b' use big-endian byte order for creating a file
+	 * 'L' read/write information using LSB2MSB bit order
+	 * 'B' read/write information using MSB2LSB bit order
+	 * 'H' read/write information using host bit order
+	 * 'M' enable use of memory-mapped files when supported
+	 * 'm' disable use of memory-mapped files
+	 * 'C' enable strip chopping support when reading
+	 * 'c' disable strip chopping support
+	 * 'h' read TIFF header only, do not load the first IFD
+	 * '4' ClassicTIFF for creating a file (default)
+	 * '8' BigTIFF for creating a file
+	 *
+	 * The use of the 'l' and 'b' flags is strongly discouraged.
+	 * These flags are provided solely because numerous vendors,
+	 * typically on the PC, do not correctly support TIFF; they
+	 * only support the Intel little-endian byte order.  This
+	 * support is not configured by default because it supports
+	 * the violation of the TIFF spec that says that readers *MUST*
+	 * support both byte orders.  It is strongly recommended that
+	 * you not use this feature except to deal with busted apps
+	 * that write invalid TIFF.  And even in those cases you should
+	 * bang on the vendors to fix their software.
+	 *
+	 * The 'L', 'B', and 'H' flags are intended for applications
+	 * that can optimize operations on data by using a particular
+	 * bit order.  By default the library returns data in MSB2LSB
+	 * bit order for compatibiltiy with older versions of this
+	 * library.  Returning data in the bit order of the native cpu
+	 * makes the most sense but also requires applications to check
+	 * the value of the FillOrder tag; something they probably do
+	 * not do right now.
+	 *
+	 * The 'M' and 'm' flags are provided because some virtual memory
+	 * systems exhibit poor behaviour when large images are mapped.
+	 * These options permit clients to control the use of memory-mapped
+	 * files on a per-file basis.
+	 *
+	 * The 'C' and 'c' flags are provided because the library support
+	 * for chopping up large strips into multiple smaller strips is not
+	 * application-transparent and as such can cause problems.  The 'c'
+	 * option permits applications that only want to look at the tags,
+	 * for example, to get the unadulterated TIFF tag information.

+ * TIFF Library.
+ * PixarLog Compression Support
+ *
+ * Contributed by Dan McCoy.
+ *
+ * PixarLog film support uses the TIFF library to store companded
+ * 11 bit values into a tiff file, which are compressed using the 
+ * zip compressor.  
+ *
+ * The codec can take as input and produce as output 32-bit IEEE float values 
+ * as well as 16-bit or 8-bit unsigned integer values.
+ *
+ * On writing any of the above are converted into the internal
+ * 11-bit log format.   In the case of  8 and 16 bit values, the
+ * input is assumed to be unsigned linear color values that represent
+ * the range 0-1.  In the case of IEEE values, the 0-1 range is assumed to
+ * be the normal linear color range, in addition over 1 values are
+ * accepted up to a value of about 25.0 to encode "hot" hightlights and such.
+ * The encoding is lossless for 8-bit values, slightly lossy for the
+ * other bit depths.  The actual color precision should be better
+ * than the human eye can perceive with extra room to allow for
+ * error introduced by further image computation.  As with any quantized
+ * color format, it is possible to perform image calculations which
+ * expose the quantization error. This format should certainly be less 
+ * susceptable to such errors than standard 8-bit encodings, but more
+ * susceptable than straight 16-bit or 32-bit encodings.
+ *
+ * On reading the internal format is converted to the desired output format.
+ * The program can request which format it desires by setting the internal
+ * pseudo tag TIFFTAG_PIXARLOGDATAFMT to one of these possible values:
+ *  PIXARLOGDATAFMT_FLOAT     = provide IEEE float values.
+ *  PIXARLOGDATAFMT_16BIT     = provide unsigned 16-bit integer values
+ *  PIXARLOGDATAFMT_8BIT      = provide unsigned 8-bit integer values
+ *
+ * alternately PIXARLOGDATAFMT_8BITABGR provides unsigned 8-bit integer
+ * values with the difference that if there are exactly three or four channels
+ * (rgb or rgba) it swaps the channel order (bgr or abgr).
+ *
+ * PIXARLOGDATAFMT_11BITLOG provides the internal encoding directly
+ * packed in 16-bit values.   However no tools are supplied for interpreting
+ * these values.
+ *
+ * "hot" (over 1.0) areas written in floating point get clamped to
+ * 1.0 in the integer data types.
+ *
+ * When the file is closed after writing, the bit depth and sample format
+ * are set always to appear as if 8-bit data has been written into it.
+ * That way a naive program unaware of the particulars of the encoding
+ * gets the format it is most likely able to handle.
+ *
+ * The codec does it's own horizontal differencing step on the coded
+ * values so the libraries predictor stuff should be turned off.
+ * The codec also handle byte swapping the encoded values as necessary
+ * since the library does not have the information necessary
+ * to know the bit depth of the raw unencoded buffer.
+ *
+ * NOTE: This decoder does not appear to update tif_rawcp, and tif_rawcc.
+ * This can cause problems with the implementation of CHUNKY_STRIP_READ_SUPPORT
+ * as noted in http://trac.osgeo.org/gdal/ticket/3894.   FrankW - Jan'11
