This pull request adds support for Khronos Textures to NetRadiant and Q3Map2, with OpenGL ES 2.0 formats, Ericsson Texture Compression version 1, and BGR/BGRA.
The patent-free Ericsson Texture Compression format will be used in the next version of Warsow to significantly reduce VRAM usage on mobile GPUs and the integrated GPU of Intel Broadwell.
