[Mesa-dev] [PATCH 0/5] GL_OES_required_internalformat

[Eric Anholt]

This series came out of fixing dEQP failures on vc4's GLES2 context.
Mesa was allowing RGB565 textures, which is only valid with
GL_OES_required_internalformat.  Rather than disable RGB565, I decided
the extension was easy enough to support.

I've sent one piglit test for renderbuffer sizing, and dEQP has tests
for whether enums get accepted for TexImage.

There's a functional question in patch #2, see the comment there, and
there's a question of whether the extension should be dummy_true in
patch #5.
