This permits consecutive path drawing or text drawing to combine
if their graphics state matches. This speeds up rendering considerably
when PDFium draws in many small parts. It also allows discarding
changes to the clip state that have no effect from draw to draw.

This adds text to the _SUPPORT_SKIA_PATHS_
variant.
The output of the test corpus has more
differences, but no feature changes or
dropouts that I can see.
The text is a bit lighter. Bungeman thinks
this is because of our support of SRGB
color, although the fonts also look different
so maybe there's more to the story.
The output looks compatible with the
variations I see in Adobe Reader and Firefox
on the same platform.
There's probably more text tuning to do.
Additionally, this turns off the caching
feature for this variation. Caching can't
work because the drawing alternates between
Skia and PDFium's native blits, so any
state caching won't know about changes
and drawing performed by the other.

PDFs draw bitmaps with alpha by supplying an
image alpha mask along side the image color data.
The alpha mask may not be the same scale as the
image data. Skia doesn't have a direct mapping
for this draw call, but can come close by using
the internal SkCompositeShader class.
This scales the alpha mask to match the size of
the image data, then puts both in the composite
shader to draw.
There are more things to do:
- Allow Alpha8 or Gray8 to draw scaled to
a matching device (blit doesn't work today)
Temporary code marked with
a TODO implements this functionality.
- Refactor PDFium to allow SkComposeShader's
components to take a matrix.
The latter goal will defer drawing so that PDFium
doesn't resize the mask, discarding resolution,
before Skia has a chance to record it.
Additionally fix drawing text with a negative
font size.

This code has several disadvantages over a more modern graphics engine:
- no SIMD support
- no GPU support
- limited quality
Further, calling this code locks in the perceived resolution, so that
the output cannot be scaled without additional loss.
By directing all bitmap drawing through
CFX_SkiaDeviceDriver::StartDIBits, Skia can handle all appropriate
bitmap optimizations.
To that end, SetDIBits and StretchDIBits now call StartDIBits.
Other changes:
Skia's bitmaps are premultiplied. PDF contains bitmaps that are
unpremultiplied. PDFium appears to use premultiplied bitmaps sometimes,
and unpremultiplied bitmaps elsewhere. Add a debug check for
unpremultiplied bits in Skia's driver, and add a utility to premultiply
PDFium's bitmaps' bits.
PDFium supports a 24 bit RGB bitmap padded to a 32 bit word. Set the
high byte so that Skia can treat this as an ARGB bitmap.
Defer the application of the alpha value to the draw call rather than
calling MultiplyAlpha where possible.
Allow the destination bitmap to be alpha 8 or argb 32.

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.

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

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.
