Some unknown software generates cross reference table with the
claimed object numbers are all off by one. Add a simple verification
function to detect this scenario, thus have a chance to rebuild
the correct cross reference table.
To avoid unnecessary checks and potiential performance hit, we only
check for the very first non free entry.

The original code caused an optimization warning when
gcc tries to get rid of 'count > m_Length - index'
in CFX_ByteStringC::Mid() while assuming there is no signed
integer overflow.
This could also be avoided once FX_STRSIZE is no longer a
signed integer type.

There are 4 types of meshes that attempt to convert the shading object into
a stream. According to spec (section 8.7.4.1 table 76), the shading object can
be a stream or a dictionary.
All of this shading code assumes it can load the mesh from a stream. The
original code just early exited if it was not a stream. We skip the call
if it is not a stream.

This CL setups up a standalone GN build. You'll need to set gn args similar to:
use_goma = true
clang_use_chrome_plugins = false
pdf_enable_xfa = true
pdf_enable_v8 = true
pdf_is_standalone = true
The third_party/pymock files are needed to make git cl upload work correctly.

StringC's are all that's needed here. Also CMap_GetString()

Do the same for CFX_WideTextBuf as well.
The name is confusing because these return CFX_ByteStringC,
not CFX_ByteString. The AsStringC naming gives parallelism with
the string types themselves, and may help to indicate that
the result is only good for the lifetime of the object being
operated upon.

This will help avoid duplicate allocation of CFX_ByteStrings
when the caller already has one. It may seem counter-intuitive
that requiring the caller to pass an allocated CFX_ByteString
rather than a static CFX_ByteStringC would improve the situation,
but due to the idiosyncrasies of std::map, the CPDF_Dictionary
methods must always do an allocation under the covers which
can't be avoided.
The changed callers in this CL are places where we would
previously demote to CFX_ByteStringC and then allocate a
a duplicate CFX_ByteString in the dictionary method.

Using these webpages as guides

http://www.antennahouse.com/antenna1/wp-content/uploads/2015/07/background-image-gradient-1.pdf
flesh out the gradient shaders to include the PostScript Type 0
sampling function and to include radial gradients. This CL makes
rendering these pages agree with Adobe Reader output.
Some of these examples use an Extend array to clip the gradient.
Skia does not currently support this natively, so construct the
clip manually for now.
Other PDF pages may construct gradients using alternate mechanisms
-- this code will continue to be refactored as those come to light.
In particular, this CL sets up the clip and matrix differently for
axial gradients and radial gradients -- while it makes sense to do
it one way only, I prefer to defer until I have more examples to
work with.

GetConstString() has sharp edges in that when applied to
a CPDF_Number, it must return null whereas GetString() returns
a the stringified number, because of the inability to
control the lifetime of the underlying allocated string.
Deleting this method showed several places where we
actually wanted a *String, not a *StringC, so we were
re-allocating a string we already had.

The few places these are called are better served by explicit
calls to CFX_ByteString() itself. This helps make Byte and
Wide strings more similar.
Also prevents fx_string.h from having any knowledge of fx_basic.h's
ByteTextBuf class.

The code is changed or had been changed to no longer generate these
warnings. It is safe to re-enabled these warnings.
In this code change, we fixed some code which generates warnings 4018
(signed/unsigned mismatch) and 4146 (unary minus operator applied to
unsigned type, result still unsigned).
Warning 4333 (right shift by too large amount, data loss) and 4345
(an object of POD type constructed with an initializer of the form ()
will be default-initialized) are no longer generated.
The same setting is applied and verified for GN build as well.

To draw paths that are stroked and filled with a pair of colors,
reduce the fill by the width of the stroke. This is implemented
with path ops subtracting the resolved stroke shape from the
fill shape. This permits rendering the result without requiring
an offscreen bitmap.
The implementation for stroke+fill requires a new entry into
the graphics engine, so a bit was added to device caps for that.
Extract the gradient information out of the axial gradient
function descriptions, and when possible, use Skia to draw
the linear gradient directly. This requires making the function
descriptions non-opaque, and adding a bit to device caps for
another entry into the graphics engine.

Patch by forshaw.
This patch adds bounds checking to the names buffer passed to GetNameFromTT.
There are observed crashes in this function where data is read outside of
the bounds allocated and passed to GetNameFromTT. There's no reason that
this function should ever try and read outside of the allocated bounds.
