- 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")
Encoder is now a library in the "encoder" directory
JavaScript wrappers now expose the entire codec: encoder, transcoder, container independent transcoding, and .basis file information
- Removing BC7 mode 6 support from transcoder (will alway use the much smaller mode 5 tables now)
- Adding BMP support
- Adding -bench mode, for development
- CMakeLists.txt file now compatible with Visual Studio 2019 (MSVC)
- For PVRTC1, we now memset() any extra blocks after the blocks we know will be transcoded into. This is done because in GL there is padding that occurs on textures smaller than 8x8.
- Removing all OpenMP usage and replacing it with a basis C++11 job system.
- Fixing TSVQ class so it can split very long "thin" clusters that before weren't being split. This improves endpoint quantization on videos and complex 2D textures.
- More frontend perf. optimizations.
Tested on OSX, Linux with gcc/clang, and Win using MSVC 2019.
The impact on the file size is enormous, and it's used to output one
line into console which isn't exposed through the API anyhow.
