Fwd: PyOpenGL-ctypes OS X

I'm a user of PyOpenGL working on Linux/OS X. Yesterday I decided to 
test PyOpenGL 3-ctypes on OS X.

The test machine is an old Powerbook Titanium G4 667 running 10.3.9! I 
took the CVS version of PyOpenGL and compile the latest version 
(1.0.3-2) of Numpy.

tests.py ran without problem:
Ran 10 tests in 3.793s

OK

And I took the time to test the demo files. Here are the results:

OpenGL/Demo
GLE/cone.py					YES
GLE/helix.py				YES
GLE/texas.py				YES
GLUT/gears.py				YES
GLUT/molehill.py			YES
GLUT/tom/arraytest.py		YES
GLUT/tom/checker.py			YES
GLUT/tom/cone.py			YES
GLUT/tom/conechecker.py		YES
GLUT/tom/conesave.py		YES
GLUT/tom/lorentz.py			NO (Bus error)
GLUT/tom/text.py			YES
NeHe/lesson1.py				YES
NeHe/lesson2.py				YES
NeHe/lesson3.py				YES
NeHe/lesson4.py				YES
NeHe/lesson5.py				YES
NeHe/lesson6.py				YES
NeHe/lesson6-multi.py		YES
NeHe/lesson13.py			(win32 specific)
NeHe/lesson18.py			YES (but "L" doesn't change lightning)
NeHe/lesson41.py			YES
NeHe/lesson42.py			YES (but slow, maybe that's normal!)
NeHe/lesson43/lesson43.py	NO (ValueError: Unable to locate true type 
font 'Test.ttf' but the font is there?)
NeHe/lesson44/lesson44.py	DON'T KNOW (The flare is visible only when 
the end of the cylinder face the screen?)
NeHe/lesson45.py			YES (after adding Terrain.bmp to the directory, it 
was not there)


I also test one of my project and I think I found a bug in 
glGenTextures. If I'm not wrong, glGenTextures is suppose to return an 
array of GLuint. But when you generates only one texture it return a 
GLuint and when you generates more then one it returns an array of 
numpy.uint32 ?

I can resume the two cases with this code:

CASE 1
...init
textures = glGenTextures(1)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])

   File "./test.py", line 164, in ?
     glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
TypeError: unsubscriptable object

CASE 2
...init
textures = glGenTextures(2)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])

   File "./test.py", line 164, in ?
     glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures[0])
ctypes.ArgumentError: argument 2: exceptions.TypeError: wrong type

BUT if you do this, it works...
...init
textures = glGenTextures(1)
glBindTexture(GL_TEXTURE_RECTANGLE_EXT, textures)


Have an idea ? The problem is probably in the def of glGenTextures in 
exceptions.py but I don't understand "annotations". So I was not able 
to patch it.

Also I did a new extension (a really easy one!) 
OpenGL.GL.EXT.texture_rectangle.

If you're curious, here is the project I did with PyOpenGL:
