using X11 extensions it should behave as defined, but some
irregularities may occur.

On wxMac passing in wx.DefaultVideoMode as the mode parameter does
nothing.  This happens because Carbon no longer has access to
DMUseScreenPrefs, an undocumented function that changed the video mode
to the system default by using the system's 'scrn' resource.
