Thanks to Colt McAnlis, for advertising one of my earlier open source texture compression libraries at GDC, and Won Chun, who originally suggested making a universal system.
I first saw using precomputed tables for quickly computing optimal encodings of solid color blocks in ryg_dxt. The method that limits the canonical Huffman codelengths to a maximum codesize was used in Yoshizaki's lharc.
I first saw using precomputed tables for quickly computing optimal encodings of solid color blocks in ryg_dxt.

### Possible improvements
The way the -q (quality) option is converted to codebook sizes is very simple (fixed formulas), and could be improved. It has a tendancy to plateue on some files.
