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.

Supports fakeBold, underline, strikethrough, mode (fill, stroke, both), size, skew, alignment (left, center, right).
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.

Reorganize how the PDF graphic state stack is managed (fixing several bugs incidentally).
Style: fix variables with underscores.
Bug: fix image matrix application order, which enabled a small refactor.

make SkDynamicMemoryWStream::getOffset and SkPDFPage::getMediaBox const

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.

The S32A_Blend_BlitRow32 function was written and unrolled in ARM
assembly to improve the rendering performance on ARM cores lacking
NEON.
Added in SkBlitRow_opts_arm.cpp.
Performance improvement about ~18% on micro benchmarking.

core_files.mk updated, but if your build does not reference that, you will
need to add SkMallocPixelRef.cpp to your list

one index array, indexing into src array and output to dst array.
Because of the scatter-gather nature, we can not do much burst/batch
reading/writing to improve the performance.
We tried Neon vector instructions. We also tried the hand optimize the compiler
generated assembly (non-neon) code. The latter seems to have better gain.
About 6% improvements, not much though...

Taking the advantage of 16 channels of each QualWord register. Also using the
software pipelining to scatter the loads/stores among vector operations.
Got roughly 70% improvements on simulation environments.
