The signed/unsigned comparison is causing the chromium windows GN build
broken.

This Cl removes the two interfaces and renames CFDE_SolidBrush to CFDE_Brush.
Uncalled methods are removed from both CFDE_Brush and CFDE_Pen and code
simplified to match.

All of the ICodec_* interfaces had a single implementation. This CL removes
the interfaces and uses the concrete classes in their place.

Attempting to open bug_434.pdf on my Linux box would fail with:
../../xfa/fxfa/app/xfa_fwltheme.cpp:96: virtual FWL_ERR
CXFA_FWLTheme::Initialize(): Assertion `__null != m_pCalendarFont' failed.
I tracked the regression back to [1].
The issue seems to be in CFX_FontManager::AddInstalledFont we will only add
one font for a given Charset. In my case I end up loading 6 charsets, but the
fonts are all strange ones. When I open the PDF, it fails to find 'Arial'
because I've registered these other fonts.
To fix this I changed the m_FaceArray into a struct of {name, chraset}. Then
we record all fonts into this list and search over that list for the charset
when needed. This allows bug_434.pdf to open and the test to pass successfully.

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.

- Using |-skew| to get positive index, which doesn't work when skew is
INT_MIN
- Incorrect logic when determining when to use |-skew| as an index.

The naming is redundant given the base type, and will stand

Shuffled the order of methods in fx_basic_wstring.cpp to
match those in fx_basic_bstring.cpp. The way to review
this patch is to diff those two files against each other.
They are beginning to converge.
Re-ordered some parameters in Concat() so that the string
comes before its length. It feels wrong otherwise.

Copy code from the agg driver so that the Skia
driver is no longer dependent on it.
The copied code doesn't in turn call
agg; it was in the agg driver for convenience.
Much of the copied code will eventually be replaced
by native Skia code, so there's not much point
in rewriting it to make it more efficient or
maintainable.

Having this happen implicitly can be dangerous because the lifetime
has to be considered; we should have caught the "red bots" in

One bit bitmaps may be black and white or may be alpha masks.
Treat alpha masks as transparent/opaque instead of black/white.

Reuse the Skia typeface on sucessive text draw calls.
This reduces the SKP size by 100x for some documents.
Note that this does not use a smart pointer for the
Skia typeface object. The downside of doing so is that
it requires all clients that include fx_font.h to also
have access to Skia.
In this specific case, it is preferable to have a
forward declared class to isolate Skia from the rest of PDFium.

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.

Compilers have good inline memcmp nowadays, so we don't
have to resort to old tricks.
Remove FXDWORD_FROM_LSBFIRST and FXDWORD_FROM_MSBFIRST
while we're at it. MSBFIRST was technically wrong due
to promotion to int.

Use FreeType instead of Direct Write on Windows. Since PDFium
currently uses the graphics engine to draw but not to measure,
the graphics engine needs to always use FreeType to get
consistent metrics.
Add a translation from PDF's blend modes to Skia's xfer modes.
Turn on subpixel positioning for text to get more precise
glyph placement.
Pass the alpha through to get proper bitmap transparency.
Address earlier nits.

More Skia driver cleanup.
Fix the GN build for Skia.
Remove unused functions from header.
Remove agg setup that is not required.
Change path construction to use the SkCanvas matrix to position the path
rather than converting the points directly.
Draw stroked paths using Skia rather than generated the filled path.
Pin the minimum stroke width to 1 px in device space to mimic PDF's stroke
dropout control.
Factor out flipped and non-flipped matrices.
Add some debugging code.
Set the bitmap filter quality to high. This helps a lot with 1 bit sources.

This is a first-cut at supporting bitmaps.
Also added a --skp option to pdfium_test to generate
a Skia picture file. The picture file can be loaded
in Skia's SampleApp, debugger, or skiaserver to
examine the generated picture.
(This also includes fixes suggested in the prior Skia CL.
My apologies for fat-fingers abandoning that one.)
