Hi,

"The assumption that the gamma ramp size matches 1 << depth is no
longer true now that the 1,024-entry gamma ramp hardware is exposed
directly to applications."

That doesn't make much sense. If the framebuffer depth doesn't match the
lookup size, then where do the extra bits come from, and how is the
lookup actually wired to the frame buffer ? Such information is
needed to be able to know what to actually put in the lookup.
