GLUT fails to import on Wayland (using EGL), but it works if you force
it to GLX:
$ echo $XDG_SESSION_TYPE
wayland
$ python3 -c 'from OpenGL.GLUT import *'
Traceback (most recent call last):
File "<string>", line 1, in <module>

<module>
from OpenGL.GLUT.fonts import *

<module>
p = platform.getGLUTFontPointer( name )
File "/usr/lib/python3/dist-packages/OpenGL/platform/baseplatform.py", line
350, in getGLUTFontPointer
raise NotImplementedError(
NotImplementedError: Platform does not define a GLUT font retrieval function
$ PYOPENGL_PLATFORM=x11 python3 -c 'from OpenGL.GLUT import *; print("no
problem")'
no problem
Looking at OpenGL.platform.egl[0] there is indeed no
`getGLUTFontPointer()` function, unlike in OpenGL.platform.glx[1] where
the function *does* exist.

The problem is not present in 3.1.5 (e.g. in Bullseye), because the
older platform detection code there does not try to detect Wayland and
so chooses GLX (which works) instead of EGL (which fails):
