problem with simplepore live visualization

[Le Qiao]

Hi,

I recently ran into a problem with live visualisation of the simplepore 
constraint using opengl. 
I tested with samples/visualization_constraints.py. Both devel and ver4.2 give 
the same error as below, this only happens when using simplepore but not other 
shapes. 

error info:

file "/opt/homebrew/lib/python3.11/site-packages/OpenGL/error.py", line 230, in 
glCheckError
    raise self._errorClass(
OpenGL.error.GLError: GLError(
err = 1283,
description = b'stack overflow',
baseOperation = glPushMatrix,
cArguments = ()
)

Cheers
Le
