Enlightenment's Evas OpenGL Now Supports S3TC Textures

Enlightenment is flying high these days with the great contributions being done by Samsung's investment into the project.

Back in April the Evas display canvas API to the Enlightenment project added support for dealing with ETC2 texture compression. ETC2 is the lossy texture compression technique developed by Ericsson that is royalty-free and part of OpenGL ES 3.0 and OpenGL 4.3. ETC2 is the way forward but not many GPUs natively support ETC2 with S3TC being the long-time, widely-used means of texture compression.

While S3TC has long been a mess for open-source GPU drivers and other projects utilizing S3 Texture Compression, Enlightenment's Evas GL engine has gained support for dealing with textures compressed via S3TC, assuming there's driver/hardware support. "Add support for DXT1, DXT3 and DXT5 textures (4 formats in total)," per this commit and other related work that landed this week within the Enlightenment Foundation Libraries.
