Log:
Branch libmythui-osd: Add some yuv blending routines.
These unpack, sub-sample and blend regions of a MythImage (preferrably
one using YUV) into a YV12 video frame. Both routines rely on the upate
region being appropriately aligned (this keeps the code simple and
fast). Despite its good looks, the MMX version is roughly 7x faster.
Refs #7650.
