Seems like I should drop this comment as well.

On a related note: there are a few more extensions that never made it
(i.e. are missing from the Khronos public spec page) but are still

- Shipped with nvidia's glxext.h, but unused in the binary driver
(version 352.21).
- Referenced in GLX_MESA_agp_offset - "GLX_NV_vertex_array_range is required"

- No hints in nvidia headers/binary.
- Referenced in GLX_EXT_texture_from_pixmap -  "Adapted spec language
from draft version of GLX_ARB_render_texture"
- The Khronos meeting minutes state "GLX_ARB_render_texture hasn't
been kept up to date, but there's no reason it can't be completed."

- No hints in nvidia headers/binary.
- No reference to in the public specs.

- No hints in nvidia headers/binary.
- Referenced by GLX_EXT_swap_control, "Based on GLX_MESA_swap_control
version 1.1"

I'm not suggesting that we should nuke these, but curious if they are
or may have been used at some point.
