Comment (by mark_kendall at btinternet.com):

 Use 3 textures for YUV texture upload

 By using 3 textures rather than one for frame upload, we avoid having to
 calculate the frame offsets  and avoid 'random' memory reads during yuv to
 rgb conversion. There appears to be no upload penalty for 3 textures
 rather than one.

 On my test system (FX5200), this yields a 15-30% performance improvement,
 depending on display size.
