We've been seeding the initial values of our registers to x+0.5,y+0.5, 1,0, 0,0,0,0 (useful values for shaders to start with) in all pipelines. This CL changes that to do so only when blitting, and only when we have a shader. The nicest part of this change is that SkRasterPipeline itself no longer needs to have a concept of y, or what x means. It just marches x through [x,x+n), and the blitter handles y and layers the meaning of "dst x coordinate" onto x. This ought to make SkSplicer a little easier to work with too. dm --src gm --config f16 srgb 565 all draws the same.
