[PyOpenGL-Users] Anyone feel like looking up glGet constant return sizes?

[Mike C. F. <mcf...@vr...>]

One of the things that PyOpenGL does when you call GL's glGet* family of 
functions is to auto-allocate the return array. It does this with a 
(manually maintained) mapping from enum/constant -> array-dimensions 
which is defined in src/glgetsizes.csv in the source tree. I have fallen 
*way* behind in keeping up with this list, so there are currently 54 
known glGet-capable constants that don't have a defined size (there are 
*other* constants that should be mapped I'm sure, but only those 
constants which show up in a formal extension description on OpenGL.org 
actually get automatically recognized as ones to annotate).

The work is mostly mechanical, you have to look up the constant, find 
the spec, read through it to see what is expected when you do glGet* for 
that constant, and determine what the array shape should be. Most of the 
glGet operations return a single value, but every once in a while you'll 
find one that returns an array, a string, etc.  If anyone feels like 
hunting down some of those constants and sending me a ping with their 
values, that would be great. If you felt like checking out the source, 
doing a few dozen, and sending a bzr patch, that would be even nicer.

The fact that I've fallen so far behind was brought to my attention by 
the fact that the constants for the various debug extensions were not 
properly mapped in glGet, so you had to manually pass in the data arrays 
to do any debug extension work.

Enjoy,
Mike
