It turns out there *is* a technical reason why the machine-generated
opengl binding is not up-to-date.
As stated in
https://community.khronos.org/t/new-xml-based-api-registry-released/70176
the specfiles are no longer being produced. Instead, they are providing
the same information coded as XML.
(I've also seen a few very old comments indicating that the old
specfiles has serious bogs in them; indeed, setphanh42 had to patch
those official specfiles before they were usable.)
It looks as if these XML files are used to produce the official C
header files, so there is a chance they're correct. And there appears
to be a python script to produce those headers, so there's hope.
So the entire program converting specfiles to Racket code will have to
be rewritten.
Or perhaps I just need a compatibility shim to translate the xml into
specfile format... xml is at least a fairly well-supported notation.
Or maybe their python code can be repurposed.
Will look into it.
