Only implemented for PNG.
Add a getter and setter, and sets the default to false in the
constructor. Also copies the setting in copyFieldsToOther.
Fix an indpendent bug where fDitherImage was not being copied in
copyFieldsToOther.
In SkScaledBitmapSampler::begin, consolidate the settings passed in
by passing a const reference to the decoder. The decoder can be
referenced for its settings of dither, unpremultiplied, and now
skipping writing zeroes. Update callers to use the new API. In png
decoder, rather than passing around a pointer to an initial
read of getDitherImage, and potentially changing it, look at the
field on the decoder itself, and modify it directly. This is a
change in behavior - now if that same decoder is used to decode
a different image, the dither setting has changed. I think this is
okay because A) the typical use case is to use a new decoder for
each decode, B) we do not make any promises that a decode does not
change the decoder and C) it makes the code in SkScaledBitmapSampler
much cleaner.
In SkScaledBitmapScampler, add new row procs for skipping zeroes. Now
that choosing the row proc has five dimensions (src config, dst config,
dither, skip writing zeroes, unpremultiplied), use a new method: each
src/dst combination has a function for choosing the right proc depending
on the decoder.
SkScaledBitmapScampler::RowProc is now public for convenience.
Remove Sample_Gray_D8888_Unpremul, which is effectively no different
from Sample_Gray_D8888.
In cases where unpremultiplied was trivial, such as 565 and when
sampling from gray, decoding may now succeed.
Add a benchmark (currently disabled) for comparing the speed of skipping
writing zeroes versus not skipping. For this particular image, which is
mostly transparent pixels, normal decoding took about 3.6 milliseconds,
while skipping zeroes in the decode took only about 2.5 milliseconds
(this is on a Nexus 4). Presumably it would be slower on an image
with a small amount of transparency, but there will be no slowdown
for an image which reports that it has no transparency.
In SkImageRef_ashmem, always skip writing zeroes, since ashmem
memory is guaranteed to be initialized to 0.
Add a flag to skip writing zeroes in skimage.
Add a regression test for choosing the rowproc to ensure I did not
change any behavior accidentally.

Replace the current constructor for creating an
SkPicturePlayback to a factory. In the factory,
check for incorrect data that would result in an invalid
playback. If the playback is invalid, return NULL, and
return NULL from SkPicture's factory as well.
Update SkTimedPicture(Playback) as well.

Adds a 'hasVertexCode' method to GrEffect and a 'fHasVertexCode' field
to GrGLProgramDesc::KeyHeader. Also adds a GrVertexEffect class that
effects have to inherit from in order to set the 'hasVertexCode' flag
and be able to emit vertex code, and updates the existing effects to
use it as needed.

Extracts a GrCustomCoordsTextureEffect class from
GrSimpleTextureEffect. This way there are no effects that can
conditionally require a vertex shader. They either always need one or
never do. Also removes kCustom_CoordsType from the CoordsType enum in
GrEffect (that enum is really only meant for coords provided by the
framework), and updates GrSimpleTextureEffect::TestCreate to make the
effect with position as well, instead of just local coords.

android_ninja {tests,bench,gm,bench_pictures,render_pictures} all build and run
fine. They build so fast I thought maybe they were broken.
Note that android_ninja with no argument is failing:
ninja: Entering directory `out/config/android-arm_v7_thumb/Debug'
ninja: error: 'lib.target/libSampleApp.so', needed by 'android/libs/armeabi-v7a/libSampleApp.so', missing and no known rule to make it
Will look into this.
