Revise some of the compositor performance improvements to improve correctness.
Implement pixel blending using a variation of Jim Blinn's no-division blending algorithm.
Move transparency type simplification further up the composition code.
Remove some unnecessary fields.
Output to YUV implementation needs revision as it is actually converting from YUV (copy of source conversion code).
