max texture size

You have to have a valid context for any of this code to work.
Depending on your platform, that would be aglGetCurrentContext or
wglGetCurrentContext. Also, don't use GLUT inside Jitter. GLUT is
for standalone applications and does not play nice with others.

You can use jit.gl.sketch with the message "glget max_texture_size" to
query this kind of stuff. Basically, take any glGet call and lop off
the GL_ of the GL enum and it should work except perhaps for for
really obscure ones.
