swscale: use 16-bit intermediate precision for RGB/XYZ conversion The current logic uses 12-bit linear light math, which is woefully insufficient and leads to nasty postarization artifacts. This patch simply switches the internal logic to 16-bit precision. This raises the memory requirement of these tables from 32 kB to 272 kB. All relevant FATE tests updated for improved accuracy.
