Code refactoring: add unified image buffer functions for doing float => byte,

byte => float, float => float, byte => byte conversions with profile, dither
and predivide. Previously code for this was spread out too much.

There should be no functional changes, this is so the predivide/table/dither
patches can work correctly.
