Mesa Now Supports S3TC Texture Compression With sRGB Color Components

Google/Chromium developer Gurchetan Singh added support for OpenGL EXT_texture_compression_s3tc_srgb support to Mesa: both core Mesa as well as the drivers -- Gallium3D and the i965 classic driver.
Google and Unity developers worked out the EXT_texture_compression_s3tc_srgb back in 2016 for using S3 Texture Compression with sRGB color components. Adding this extension to Mesa ended up being quite trivial at a few lines of code.
This S3TC sRGB support comes just days after Intel landed for sRGB / FP16 support, including the EXT_sRGB_write_control extension. This latest Mesa work will be found in the 19.1 release due out next quarter with the 19.0 branching having occurred last week.
