From: Nanley Chery <nanley.g.ch...@intel.com>

According to the extensions table and our glext headers,
OES_compressed_ETC1_RGB8_texture is only supported in
GLES1 and GLES2. Since we may give users a GLES3 context
when a GLES2 context is requested, we also allow this
extension for GLES3 as well.

I've updated the commit's subject and comment to be clearer. I assume
the R-b on the first patch still applies?
