Simplify shader paint alpha modulation.
We don't need to do any of this funky swap, load, srcin nonsense. We've got a perfectly good scale_constant_float stage just perfect to be used instead.
While we're at it, we only need to modulate by paint alpha if the paint's not opaque. x*1== x...
This puts the (x,y) inputs to shaders in (r,g) where they expect them. It also frees (dr,dg,db,da) for use by the shader. Might be handy for bilerp.
