- Optimized ETC1S encoder (3-4.5x faster) - Added optional SSE 4.1 support to encoder - Switched from std::vector to a custom vector in the encoder and transcoder - Added CppSPMD (SSE only for now) - UASTC RDO is now more effective, but the command line parameter controlling qualiy has changed (to "lambda")
