-// Tone curves are powerful constructs that can contain curves specified in diverse ways.
-// The curve is stored in segments, where each segment can be sampled or specified by parameters.
-// a 16.bit simplification of the *whole* curve is kept for optimization purposes. For float operation,
-// each segment is evaluated separately. Plug-ins may be used to define new parametric schemes,
-// each plug-in may define up to MAX_TYPES_IN_LCMS_PLUGIN functions types. For defining a function,
-// the plug-in should provide the type id, how many parameters each type has, and a pointer to
-// a procedure that evaluates the function. In the case of reverse evaluation, the evaluator will
-// be called with the type id as a negative value, and a sampled version of the reversed curve

-// with respect to all the coordinates. This is know as the Jacobian

-// linear approximation will give a "better guess" for the zero of f. Thus let y=0,
-// and since y0=f(x0) one can solve the above equation for x. This leads to the
-// Newton's method formula:
-//
-// xn+1 = xn - A-1 f(xn)
-//
-// where xn+1 denotes the (n+1)-st guess, obtained from the n-th guess xn in the

-
- L* = 116*f(Y/Yn) - 16 0 <= L* <= 100
- a* = 500*[f(X/Xn) - f(Y/Yn)]
- b* = 200*[f(Y/Yn) - f(Z/Zn)]

- (841/108)*t + (16/116) 0 <= t <= (24/116)^3

- Reverse transform is:
-
- X = Xn*[a* / 500 + (L* + 16) / 116] ^ 3 if (X/Xn) > (24/116)

- Implementation
- --------------
-
- PostScript does use XYZ as its internal PCS. But since PostScript
- interpolation tables are limited to 8 bits, I use Lab as a way to
- improve the accuracy, favoring perceptual results. So, for the creation
- of each CRD, CSA the profiles are converted to Lab via a device
- link between profile -> Lab or Lab -> profile. The PS code necessary to
- convert Lab <-> XYZ is also included.
-
-
-
- Color Space Arrays (CSA)
- ==================================================================================
-
- In order to obtain precision, code chooses between three ways to implement
- the device -> XYZ transform. These cases identifies monochrome profiles (often
- implemented as a set of curves), matrix-shaper and Pipeline-based.
-
- Monochrome
- -----------
-
- This is implemented as /CIEBasedA CSA. The prelinearization curve is
- placed into /DecodeA section, and matrix equals to D50. Since here is
- no interpolation tables, I do the conversion directly to XYZ
-
- NOTE: CLUT-based monochrome profiles are NOT supported. So, cmsFLAGS_MATRIXINPUT
- flag is forced on such profiles.
-
- [ /CIEBasedA
- <<
- /DecodeA { transfer function } bind
- /MatrixA [D50]
- /RangeLMN [ 0.0 cmsD50X 0.0 cmsD50Y 0.0 cmsD50Z ]
- /WhitePoint [D50]
- /BlackPoint [BP]
- /RenderingIntent (intent)
- >>
- ]
-
- On simpler profiles, the PCS is already XYZ, so no conversion is required.
-
-
- Matrix-shaper based
- -------------------
-
- This is implemented both with /CIEBasedABC or /CIEBasedDEF on dependig
- of profile implementation. Since here there are no interpolation tables, I do
- the conversion directly to XYZ
-
-
-
- [ /CIEBasedABC
- <<
- /DecodeABC [ {transfer1} {transfer2} {transfer3} ]
- /MatrixABC [Matrix]
- /RangeLMN [ 0.0 cmsD50X 0.0 cmsD50Y 0.0 cmsD50Z ]
- /DecodeLMN [ { / 2} dup dup ]
- /WhitePoint [D50]
- /BlackPoint [BP]
- /RenderingIntent (intent)
- >>
- ]
-
-
- CLUT based
- ----------
-
- Lab is used in such cases.
-
- [ /CIEBasedDEF
- <<
- /DecodeDEF [ <prelinearization> ]
- /Table [ p p p [<...>]]
- /RangeABC [ 0 1 0 1 0 1]

- /MatrixABC [ 1 1 1 1 0 0 0 0 -1]
- /WhitePoint [D50]
- /BlackPoint [BP]
- /RenderingIntent (intent)
- ]
-
-
- Color Rendering Dictionaries (CRD)
- ==================================
- These are always implemented as CLUT, and always are using Lab. Since CRD are expected to
- be used as resources, the code adds the definition as well.

-// The pthreads API has an initialization macro that has no correspondence to anything in
-// the windows API. By investigating the internal definition of the critical section type,
-// one may work out how to initialize one without calling InitializeCriticalSection().
-// The trick here is that InitializeCriticalSection() is not allowed to fail. It tries
-// to allocate a critical section debug object, but if no memory is available, it sets
-// the pointer to a specific value. (One would expect that value to be NULL, but it is
-// actually (void *)-1 for some reason.) Thus we can use this special value for that
-// pointer, and the critical section code will work.
-
-// The other important part of the critical section type to initialize is the number
-// of waiters. This controls whether or not the mutex is locked. Fortunately, this
-// part of the critical section is unlikely to change. Apparently, many programs
-// already test critical sections to see if they are locked using this value, so
-// Microsoft felt that it was necessary to keep it set at -1 for an unlocked critical
-// section, even when they changed the underlying algorithm to be more scalable.
-// The final parts of the critical section object are unimportant, and can be set
-// to zero for their defaults. This yields an initialization macro:
