- weighted cuda compressor.
- faster and better BC3n compressor - add normal map flag to DDS files that store normal maps. - stop using RXGB fourcc code. - move tools to tools/ - add temptative config dialog for UI based tool. - add experimental normal map mipmap generation. - start adding support for input dds files in nvcompress. - many other small fixes and cleanup.
