Bug 616469 - Video sync is slow because of slow yuv2rgb conversion. README and patch r=doublec a=blocking-fennec

This color conversion code is from the Chromium open source project available here:

http://code.google.com/chromium/

The code comes from svn revision 638400 on 2010-10-26.

The code was copied from a Chromium svn checkout using the 'update.sh' script which then applies patches for our build and to add dynamic CPU detection.

convert.patch: Change Chromium code to build using Mozilla build system.
               Add runtime CPU detection for MMX
               Move default C implementation to work on all platforms.
               Change Chromium code to allow a picture region.
               The YUV conversion will convert within this 
               picture region only.
               Add YCbCr 4:4:4 support

arm.patch: Add YCbCr to rgb16_565 conversion support, bug 616469
