Recent refactoring for the BC7/BPTC compressor caused some errors. We can avoid this in the future by implementing a few unit tests:

Make sure that a simple white, black, red texture compresses and decompresses exactly.
Make sure that the kodim images each compress to within some PSNR.
Test a few of the quality levels. If the error from the initial endpoint selection is huge, the simulated annealing actually does a really good job in picking better endpoints. If it's not so big, then the simulated annealing doesn't have an effect.
