I think the term "bindless" might cause confusion with the OpenGL concepts of
bindless textures. Could we choose another name? ProduceFromTextureCHROMIUM?
Something else? I think ideally the old entry point would be removed once all
call sites are switched to the new one. Perhaps it could just be temporarily
called glProduceTextureNewCHROMIUM or glProduceTexture2CHROMIUM. Then everyone
could be switched over to the new one; the old one could be replaced with the
new signature; everyone switched back; and the new temporary one deleted.

Nit: the GL-y way is to have target before texture.

     GLenum target, const GLbyte* mailbox);

The signature of the function pointer doesn't match the prototype above.

     GLenum target, const GLbyte* mailbox);
