Summary: glutMouseFunc handler button arg

Initial Comment:
A handler defined on a modified version of the 
"simple" demo:

    def on_mouse(self, button, state, x, y):
        print (button, state, x, y)

when used via glutMouseFunc(self.on_mouse) the button 
arg is always 0, the others are what is expected. 
That is, I get output like:

(0, 0, 198, 203)
(0, 1, 114, 262)
(0, 0, 137, 43)
(0, 1, 207, 105)
(0, 0, 168, 30)
(0, 1, 162, 240)
(0, 0, 263, 220)
(0, 1, 87, 130)
(0, 0, 149, 230)
(0, 1, 157, 88)

I'm new to GL, so my apologies if I'm missing an 
additional initialisation or handler step.

Tested on Win32 and Linux (RedHat).  Works fine.  The 
C code used to interface to glutMouseFunc and the 
callback is trivial, i.e. just passes the arguments 
straight through. 

Try this C program so we can determine if its' a 
PyOpenGL problem.  This will probably work to compile

gcc -o test test.c -lglut -lGL -lGLU

That test script didn't work - PyOpenGL_info.html attached.

Try out this test script.  Works on my system.  If it 
doesn't work on your system upload PyOpenGL_info.html 
produced by OpenGL/scripts/info.py
