This hopefully makes it less confusing what the description of a point is.
Currently we have defines for the types, which is confusing because a point
can only be one of the three. And it is mixed up with whether the point is
closing a figure or not.

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.
All corpus tests draw equivalently with caching enabled or disabled.
Change the member order in CPDF_PageRenderContext so the device is
flushed before the referencing annotation is deleted.
Add more printf style debugging for test draws.

Allow shading to use Skia for some gradients;
linear, radial, and coons patch.
The corpus uncovered a few gradient-related bugs
in the Skia driver which are fixed as well.
Fix corpus 11.pdf by ignoring zero area
filled paths. PDFium uses CFX_PathData::GetZeroAreaPath()
to determine if a path that doesn't enclosing anything
should be drawn anyway, and CFX_AggDeviceDriver::GetDriverType()
returns 1 so that the empty path is tweaked so that
it doesn't draw too often.
There are no tests in the corpus that show
the utility of this approach; 11.pdf draws correctly
if the zero area paths are ignored.
Standardize debugging output so that
a separate tool can visualize it.

This CL moves the IFWL classes that do not have CFWL class buddies to have the
CFWL name. This CL leaves the tree in a weird state of having CFWL be two
hierarchies, one of which is intertwined with the IFWL hierarchy. This should
be commited just before the CL to move the rest of IFWL to CFWL.

PDF can specify a negative font size
to change the y-axis for text. Add
support in the Skia driver for that.
The cached form for text and paths
had fallen out of sync with the uncached
code used by skiapaths, so sync that
up so that the mainline skia setting
has those bug fixes as well.
This does not fix the underlying bug in
528103, but gets Skia on parity with
native PDFium text rendering. The bold
text is still drawn in the wrong place.

Transparencies and bitmap patterns need to be
unpremultiplied after Skia renders them so
that PDFium can use its own compositing.
Also added some linear (i.e. axial) gradient
support, although its unclear if any of the

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.

All corpus tests draw reasonably well.
There are pixel differences, but no missing
features or large scale errors.
This was verified by running run_corpus_tests.py
on skiapaths and agg build dirs, then running
the skdiff tool to generate a report of the
pixel difference. For example, after running
$ ninja -C out/skia skdiff
$ ./out/skia/skdiff /repo/pdfium/out/agg/gen/pdfium/testing/corpus/ /repo/pdfium/out/skiapaths/gen/pdfium/testing/corpus/ ~/aggskiadiffs

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.
