- MODIFIED to calculate coeffs from currently selected color space.
- MODIFIED core to be a macro which you spec the output format.
- ADDED UYVY conversion which is never called due to some thing in SWSCALE.
- CORRECTED algorithim selection to be strict on input formats.
- ADDED runtime detection of altivec.

- OPTIMIZED DST OUTPUT cache/dma controls. we are pretty much
- guaranteed to have the input video frame it was just decompressed so
- it probably resides in L1 caches. However we are creating the
- output video stream this needs to use the DSTST instruction to
- optimize for the cache. We couple this with the fact that we are
- not going to be visiting the input buffer again so we mark it Least
- Recently Used. This shaves 25% of the processor cycles off.
