- Change SkGraphicState to track and set the blend mode (xfermode) for modes built in to PDF (non porter duff modes + src over).
- Add SkXfermode::asMode() to retrieve xfermode as an enum for non porter duff modes.
- Move SkXfermode.cpp around a bit to support asMode() -- Generally move utility functions toward the top of the file.
- Make SkPDFFormXObject an isolated transparency group, as it used for saveLayer, which draws on transparent, not the device background.
- Set the graphic state in drawDevice and drawBitmap in order to get the right xfermode and alpha.

SkSafeRef() and SkSafeUnref().
This is basically a bug waiting to happen. An optimizing compiler can remove
checks for null on "this" if it chooses. However, SkRefCnt::safeRef() relies on
precisely this check...
void SkRefCnt::safeRef() {
if (this) {
this->ref();
}
}
Since a compiler might skip the if-clause, it breaks the intention of this
method, hence its removal.
static inline void SkSafeRef(SkRefCnt* obj) {
if (obj) {
obj->ref();
}
}
This form is not ignored by an optimizing compile, so we use it instead.

Sorry this is such a large CL. It was very exploratory for me to make this
work.
- Add an interface to SkFontHost to retrieve font information and provide NULL implementations on all platforms except Linux.
- Segment large Type 1 fonts into fonts with shared resources with 255 glyphs each.
- Convert the various Type 1 formats to the form PDF wants.
- Update font as we draw text instead of as part of the graphical state.
- Remove built-in font support, we can't really use it.
Other changes I can pull out to a separate CL if you like.
- Add SkTScopedPtr class.
- Fix double free of resources.
- Fix bug in resource unique-ifying code.
- Don't print anything for any empty clip path.
- Fix copy paste error - MiterLimit.
- Fix sign extension bug in SkPDFString
- Fix FlateTest rename that was missed on a previous commit.

The regression was due to the fact that we were calling PlatformColorProc() for
every span (which in turns makes CPUID, a fairly expensive call). Since we draw
a lot of rects, and rects have 1-pixel wide spans for the vertical segments,
that's a lot of CPUID.
Fixed by cacheing the result of PlatformColorProc(), as is done for the other
platform-specific blitters.

[Patch from weiwei.li@intel.com]
SSE2 optimization has been added by Stephen White before, this improves the skia
performance on SSE2-supporting platform. (please refer to below issues)
Issue 171055: More SSE2ification
Issue 157141: More SSE2ification
Issue 150060: minor tweaks to SSE2 code for -fPIC
Issue 144072: SSE2 optimizations for 32bit blending blitters
This CL implements SSE2 optimizations for the 32bit Color operation. Like above
issues, it uses CPUID to detect for SSE2 and changes the platform procs at
runtime as well. The 32bit Color operation is heavily used on Chrome HTML5
canvas operations. Take Microsoft IE test drives Pulsating Bubbles as example
(http://ie.microsoft.com/testdrive/Performance/PulsatingBubbles/Default.xhtml),
if running this cases on Chrome, the overhead of 32bit Color operation is about
40~50%. So this CL will make skia performance more better, and also make Chrome
HTML5 canvas performance more better.
Additional, this CL has passed the skia bench & tests validation, the result is
pretty good. We also apply this CL to the latest chromium, and re-run Microsoft
IE test drives Pulsating Bubbles, the performance is improved by almost 9~10%.

This patch adds four methods to SkBitmap. There are two functions to return
"safe size", defined as the number of pixels from the value returned by
getPixels() to the end of the allocated buffer.
There is one version of fillPixels() to copy the bitmap instance into an
external buffer (with specified size, and using specified stride), and another
fillPixels() to copy from an external buffer to the instance bitmap. In the
latter case the specified height, width and pixel format must match that used by
the bitmap instance, although the specified stride may be any value at least as
large as the minimum stride for the specified geometry. It is assumed that the
external buffer is of size at least (height - 1)*stride + width *
bytesPerPixel.
Both fillPixels() functions return false if the copy is not possible with the
specified parameters.

Missing is drawFontOnPath and font lookup and embedding.
Changed SkPDFString to support how it is used from drawText methods.
Moved compile assert into SkTypes.
Moved constants and utility function used to support fakeBold, underline, and strikethrough into higher level locations.

The '#include "SkGLDevice.h"' from include/core/SkDevice.h requires internal
Skia code to be added to the include search paths when using the deprecated API.
This change adds back SkGLCanvas.cpp to avoid exposing SkGLDevice.h to the
public API.
The change also includes an explicit virtual destructor on SkDeviceFactory to
silence a -Wnon-virtual-dtor warning and allow for -Werror.

These are not the capabilities of the factory, but of the device. Additionally, it is more often needed when you have a device then when you have a factory, which caused creating of a new factory.

The previous change made it difficult to inherit from SkCanvas without leaking memory. By making SkDeviceFactory not reference counted, the right thing happens more naturally, just NewCanvas : public SkCanvas(new NewDeviceFactory()) {...}

Methods or classes that should go away are marked deprecated. The only thing I know of that breaks backward compatibility is SkCanvas((SkDevice*)NULL), but that is fairly unlikely to occur in the wild because that constructor had a default value of NULL.

- when the previous point in the path and (x1, y1) are coincident
- when (x1, y1) and (x2, y2) are coincident
These cause the setNormalize() calls to leave the "before" and "after" vectors
uninitialized, respectively, which are then used to compute cosh and sinh.
I chose to implement HTML5 canvas behaviour for these cases (as well as for the
case where all three points are collinear): add a line to the first point, and
bail. I think this is ok, since skia is mostly used for HTML5 browsers, and
this case is degenerate anyway.
