Summary: Probable int/int32 problem with version 3.0.0a4

Initial Comment:
With version 3.0.0a4, compiled on Linux 64 bits,
lesson18 in Demo/NeHe dies with:

Traceback (most recent call last):
  File "lesson18.py", line 302, in ?
    main()
  File "lesson18.py", line 294, in main
    InitGL(640, 480)
  File "lesson18.py", line 106, in InitGL
    LoadTextures()
  File "lesson18.py", line 76, in LoadTextures
    glBindTexture(GL_TEXTURE_2D, textures[0])   # 2d
texture (x and y size)
ctypes.ArgumentError: argument 2: exceptions.TypeError:
int expected instead of numpy.int32 instance


This may suggest that an explicit signature with int32
is needed (at least to accommodate 64 bits architectures,
since 32 bits architectures will find both int and int32
equivalent).

A fix can possibly made in several places, but
I would think that changing the signature of
glBindTexture for its secnd argument to int32 is 
what is needed.
