Beginning of support for texture rectangles.
Adds support for importing a RECTANGLE texture into Skia via GrTexureProvider::wrapBackendTexture().
Tests read/writing pixels, copySurface, and clear.
Does not add support for texturing from a RECTANGLE texture as the coords will be incorrectly normalized.
