David Schleef 4ee3afc051 cog: Improve RGB<->YCbCr matrixing 
YCbCr->RGB now has a 'bits' setting, which controls the number
of bits used for the matrix coefficients.  Choices are 6 or 8.
6 is low quality, but faster.
RGB->YCbCr now works.  Always works in 8 bit, since it's the same
speed as 6 bit.

David Schleef 3c870a7a6c cog: reset cache instead of returning NULL 
Returning NULL makes things crash.  Resetting the cache
makes things run slow.  Still an underlying bug somewhere,
but not critical.
