mesa: Add linear ETC2/EAC to the compressed format list with ES3 compat.
GL_ARB_ES3_compatibility brings ETC2/EAC formats to desktop GL. The meaning of the GL compressed format list is pretty vague - it's supposed to return formats for "general-purpose usage". (GL 4.2 deprecates the list because of this.) Basically everyone interprets this as "linear RGB/RGBA". ETC2/EAC meets that criteria, so while we shouldn't be required to add it to the list, there's also little harm in doing so, at least on platforms with native support. I doubt anyone is using this list for much anyway, so even on platforms without native support, it's probably not a big deal. Makes the following GL45-CTS.gtf43 tests pass: * GL3Tests.eac_compression_r11.gl_compressed_r11_eac * GL3Tests.eac_compression_rg11.gl_compressed_rg11_eac * GL3Tests.eac_compression_signed_r11.gl_compressed_signed_r11_eac * GL3Tests.eac_compression_signed_rg11.gl_compressed_signed_rg11_eac * GL3Tests.etc2_compression_rgb8.gl_compressed_rgb8_etc2 * GL3Tests.etc2_compression_rgb8_pt_alpha1.gl_compressed_rgb8_pt_alpha1_etc2 * GL3Tests.etc2_compression_rgba8.gl_compressed_rgba8_etc2 Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Eduardo Lima Mitev <[email protected]>
