Re: Re[20]: OpenGL Linux SIGTRAP wxWidgets-3.2*

If someone has the same problem and searches for a solution.

My current solution in Wings is:
After a reparent that somehow involves the wxGLCanvas, i.e. a direct
reparent of the wxGLCanvas or
a grandparent of the wxGLCanvas use wxGLCanvas::CreateSurface() and
recreate the wxGLContext::new( with previous context )

After a reparent that does not involve the wxGLCanvas or its grandparents,
do NOT call wxGLCanvas::CreateSurface() because that will
fail (return false) for some unknown reason and all opengl calls will
return errors.

So I finally have a solution that works on Ubuntu-20 with EGL as the OpenGL
backend.
