- Fixing minor block artifacts on pure 2 color B&W blocks when transcoding to BC1/BC7. This was caused by the ETC1S blocks using extreme ETC1S settings: codetable 7 (the one with the largest intensity deltas), using blocks with selectors that took up the full range (0-3), but the blocks only actually used the two outlier colors (0 and 3 only). The ETC1S->BC1/BC7 table based format conversion system doesn't realize that only the outlie colors were going to be used (i.e. not all 4 colors, just the outer 2), and so the quality of the transcoded block suffered because pure black could not be mapped. In BC7 mode, we now switch to pure BCT (block truncation coding) for any blocks with <= 2 unique colors, independent of their selectors.

Important: Changing the Basis file version, so any existing files will need to be recompressed!

kodim20.basis

Major compression performance/quality improvements, for a 15-35% or so decrease in file size for the same Y PSNR/SSIM. The basis file format has changed due to these optimizations.
