add (x,y) params to shader program()
This should work, though I need to do a little more work to get programs
that use x to JIT. It shouldn't be bad, probably done tomorrow.
I've added a demo y-gradient to the SkVMBlitter GM.
We may not need an explicit CTM parameter, just effects that chain into
each other changing (x,y) as they go? I guess that depends on whether
we want to specialize blitters on the matrix type any more than how we
get the shader coordinates.
