David Schleef 277699bd2a cog: Add color matrix to RGB->YCbCr conversion 2009-10-24 11:38:42 -07:00
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.
