[Mesa-dev] [PATCH v2 20/29] mesa/main: do not allow type_2_10_10_10_REV enums before gles3

[Erik Faye-Lund]

ctx->Extensions.EXT_texture_type_2_10_10_10_REV is set regardless of
the API that's used, so checking for those direcly will always enable
extensions when they are supported by the driver.

There's no corresponding extension for OpenGL ES 1.x/2.0, so we
shouldn't allow these enums there.
