[CDI] Significant optimization:
- Removed redudant call to mcd212_process_regions
- Refactored mcd212_process_regions to fill scanline-wide buffers for region
flags and pixel weights, eliminating costly recalculation for every pixel
- Refactored color calculations to use separated R/G/B buffers to avoid
constant bit-shifting / boolean arithmetic
- Un-inlined certain functions to possibly improve cache performance with
better code locality
- Unrolled plane enable/disable logic to avoid frequent array lookups
Performance has increased on a 1.86GHz Core 2 Duo from 28% in a profile build
to 75% profile build, flat 100% on a non-profile build

not weighting. This makes many games look considerably better.

flipping out
