If wx.DefaultVideoMode is passed in as the mode parameter, the defined
behaviour is that wx.Display will reset the video mode to the default
mode used by the display.  On Windows, the behavior is normal.
However, there are differences on other platforms. On Unix variations
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.
