Pull request: Add KTX and ETC1 texture support
Since GitLab says "selected branches have no common commit", I can't create a real merge request here, so it's located on GitHub, but the master HEAD is the same here.
We're going to use Khronos Textures with patent-free Ericsson Texture Compression in the next version of Warsow that will be available on mobile (also Intel Broadwell supports ETC), so I wrote a patch for NetRadiant and Q3Map2 that adds support of KTX with GLES2 formats, ETC1 and also BGRA.
Also the Warsow game pack is now located on Warsow GitHub and lists KTX as a supported format.
