[Mesa-dev] [PATCH 00/18] Implement GL_ARB_multi_bind

[Fredrik Höglund]

So here is my take on GL_ARB_multi_bind.

I tried to come up with names for the new hash table functions that
don't suggest that they should be used to do unlocked insertions/lookups.
I'm not entirely happy with the ones I came up with though, so I'm
hoping someone will have better suggestions.

When binding 32 textures glBindTextures() seems to be about three times
faster than calling glActiveTexture() + glBindTexture() in a loop.
When binding 4 textures it's about twice as fast.

I hope to land this series this week if there are no major issues.

Note that I haven't been able to test the glBindImageTextures()
implementation.
