IMHO, this would not be a good place to make this call, as it must be
called before any other X calls, and there are very few situations I can
think of where a vtkXOpenGLRenderWindow is the first X-related object
created in an app. Another solution is to make the call from your own
program, or better-yet to make sure that you only modify the render
window from a single thread.
