Unsigned integer and integer sampler support

[andyc]

Hi,

I have a patch against yesterday's head with some support for unsigned
integer uniforms and for signed and unsigned integer sampler types
here:

http://www.cs.ucl.ac.uk/staff/Andrew.Cox/code/g3d/patches/g3d_patch3.diff

As with my last patch, integrating this upstream would ease my life
knowing that I could pull your latest changes. There is one
potentially difficult part of it however:

I needed that line to get the version of GLEW that you guys distribute
(and possibly any other version of it: not sure) to give me the GL3
features that I am exposing through G3D. I don't know if that would be
a problem for the two cases of someone either building or running G3D
on a machine that doesn't have a GL3 implementation installed.

Best,
Andrew

I made the GLEW change and am testing it on a GL2 machine. I filed
the other diff as a feature request.
