- PVRTC2 RGBA support added. This format looks OK if the texture has a very simple alpha channel (like simple opacity mask). The texture should use premulitplied alpha, otherwise on alpha=0 pixels the color channel may slightly leak into the alpha channel due to issues with the PVRTC2 format itself. Transcoding is fast unless the texture's alpha channel is very complex.
It's a tossup whether PVRTC1 or PVRTC2 would look better for alpha textures.
- ETC2 EAC R11/RG11 (unsigned) support checked in. Thanks to Juan Linietsky for suggesting it.
- The format enum names have changed, but I tried to keep compatibility with old code. The actual values haven't changed so Javascript code should work without modifications.

- We're now using "enum class transcoder_texture_format" instead of "enum transcoder_texture_format" in basisu_transcoder.h
- Fixed a couple encoder bugs (one assert in basisu_enc.h), and a uninitialized variable issue in the frontend. Neither issue would cause corrupted files or artifacts.
- FXT1 RGB support is checked in, for Intel/3DFX GPU's. Mostly for completeness and to test block sizes other than 4x4.
