Fix blend filters when input textures are "sloppy" (approx scratch texture match)
Add a new test case to gm/imagefiltersgraph, and reduce its size.
NOTE: this will require new baselines for the imagefiltersgraph GM.

for filters with a single image input. This provides functionality to store,
flatten and unflatten a single SkImageFilter input, as well as to recursively
evaluate it on the CPU or GPU. The following classes were re-parented to
implement DAG connectivity: SkBlurImageFilter, SkDilateImageFilter,
SkErodeImageFilter, SkColorFilterImageFilter. The constructors for each
have been appended with a new parameter, representing the input filter
(default NULL).
This change also implements an arbitrary SkBitmap input source for filtering,
SkBitmapSource.
NOTE: This CL will require gyp file changes when rolling past this revision.
