The new bit is added because... OES_texture_buffer is a combination of
GL_ARB_texture_buffer_object, GL_ARB_texture_buffer_range, and
GL_ARB_texture_buffer_object_rgb32?  Could you mention that in the
commit message (if it's not too late)?

Also... is there any hardware that supports only a subset of those
extensions?  I'd be tempted to just have one flag for all of them.
