R8 should have the gles3 support case here.

We get RG and friends in API_OPEGNES2 because of GL_EXT_texture_rg.
Only API_OPENGLES loses.
Oops, I was reading the return logic flipped. The unsized formats
should get banned for gles, right?
Gak. The quirks of ES frustrate the crap out of me. You are, of

Accepted by the <internalformat> parameter of RenderbufferStorage
and RenderbufferStorageMultisampleAPPLE:
