+  Altivec Acceleration for Color Space Conversion revision 0.2
+
+  convert I420 YV12 to RGB in various formats,
+    it rejects images that are not in 420 formats
+    it rejects images that don't have widths of multiples of 16
+    it rejects images that don't have heights of multiples of 2
+  reject defers to C simulation codes.
+
+  lots of optimizations to be done here
+
+  1. need to fix saturation code, I just couldn't get it to fly with packs and adds.
+     so we currently use max min to clip
+
+  2. the inefficient use of chroma loading needs a bit of brushing up
+
+  3. analysis of pipeline stalls needs to be done, use shark to identify pipeline stalls
+
+
+  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.
+
+  ADDED altivec_yuv2packedX vertical scl + RGB converter
+
+  March 27,2004
+  PERFORMANCE ANALYSIS
+
+  The C version use 25% of the processor or ~250Mips for D1 video rawvideo used as test
+  The ALTIVEC version uses 10% of the processor or ~100Mips for D1 video same sequence
+
+  720*480*30  ~10MPS
+
+  so we have roughly 10clocks per pixel this is too high something has to be wrong.
+
+  OPTIMIZED clip codes to utilize vec_max and vec_packs removing the need for vec_min.
+
+  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.
+
+  Now MEMCPY is the largest mips consumer in the system, probably due
+  to the inefficient X11 stuff.
+
+  GL libraries seem to be very slow on this machine 1.33Ghz PB running
+  Jaguar, this is not the case for my 1Ghz PB.  I thought it might be
+  a versioning issues, however i have libGL.1.2.dylib for both
+  machines. ((We need to figure this out now))
+
+  GL2 libraries work now with patch for RGB32
+
+  NOTE quartz vo driver ARGB32_to_RGB24 consumes 30% of the processor
+
+  Integrated luma prescaling adjustment for saturation/contrast/brightness adjustment.
