A cheap trick is to just set the EyeAngle to zero when you want to turn
off stereo.  Otherwise, yes, you will have to destroy and recreate both
the wxWindow and the vtkRenderWindow every time you switch.

With some vendors' OpenGL drivers you can create a StereoCapableWindow
and just use StereoRenderOn()/Off() to switch, but some other drivers
will spew garbage if you do a non-stereo render inside a stereo context.

There might also be some funky stuff you need to keep the wxWindow 'erase'
from causing flicker, but this might just be for the GTK version of
wxWindows.  It should all be in the python script.
