pass more information to shaders
If we're going to write an image shader, we're going to need to know the
matrix and some bits of the paint.
Instead of all possible information, I decided to pass just what the
image shader needs for now, and will pass along more as I go.
I've added a stub implementation of SkImageFilter as a way to make sure
I'm threading everything it'll need through.
