Add an option to create unpremultiplied bitmaps.
Currently they cannot be used directly by Skia, but
the pixels can be used elsewhere.
SkImageDecoder:
Add functions to require unpremultiplied output
and query the presence of the requirement
SkImageDecoder_libpng:
SkImageDecoder_libwebp:
SkImageDecoder_WIC:
Respect the requirement for unpremultiplied output.
TODO: Fix SkImageDecoder_CG.
SkScaledBitmapSampler:
Add procs to skip premultiplication and a boolean
parameter to use those procs.
ImageDecodingTest:
Test unpremultiplied bitmap decoding.
SampleUnpremul:
Add a sample which allows visually comparing between the
unpremultiplied version (copied into a premultiplied bitmap,
since drawing unpremultiplied is not currently supported)
and a premultiplied version of image files.
gm.h:
Add a getter for the resource path, so Samples can use it.
As of patch set 13, https://codereview.chromium.org/16816016/
and https://codereview.chromium.org/16983004/, which were
approved separately.
