[Mesa-dev] [PATCH 1/2] st/mesa: expose GL_OES_texture_view

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

For format fallbacks like ETC and ASTC, switching between sRGB and linear
decoding is undefined, or at least is not bit-exact. Same as
EXT_texture_sRGB_decode on GLES.

There are no piglit or dEQP regresssions.
