Brian Salomon 30970525fd At SkDevice level and below use SkBlender instead of SkBlendMode 
Draws that take a primitive with colors (vertices, patch, atlas) allow
the user to specify how the primitive color is blended with SkShader.

At the public level the blend is specified as SkBlendMode. This change
moves the implementation at SkDevice level over to SkBlender.

Future changes to the existing APIs or future APIs could allow clients
to specify SkBlenders instead of SkBlendMode. THis would would allow for
programmable blending between shader and primitive color.

SkShader_Blend now recognizes if it was constructed with a Mode blender
and extracts the mode enum.

SkBlender_Base::asFragmentProcessor no longer assumes that the dstFP's
input color should be args.fDestColor. Instead the caller
must configure that if desired. (We don't want this for drawAtlas, etc).
