Good catch; I missed those entirely.

As for the comments, looks like the assembly-like instructions didn't
make the transition. It's probably a good idea to retain those, as the
macro-driven shader code is extremely hard to parse for a new-comer
otherwise.

Also, IIRC, planar and packed Xv actually uses identical pixel
shaders, so the two can probably be merged into one.

I would also like to suggest grouping the files more logically by
subcomponent and function as opposed to one-per-file.

I reckon that would be part of the shader compiler drop?
