Uhm, well, it isn't that easy. Unifying that looks like a big job in
itself. pixel_ops.h as-is isn't very helpful for xen-framebuffer. The
xen-framebuffer macro isn't very useful to others.
What IMHO would be most useful is a set of generic conversion functions,
operating on scanline level, much like the ones created by
vga_template.h, but without dependencies on vga.c internals.
cheers,
Gerd
