Changes the video mode of this display to the mode specified in the
mode parameter.
If wxDefaultVideoMode is passed in as the mode parameter, the defined
behaviour is that wxDisplay 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 wxDefaultVideoMode as the mode parameter does
nothing. This happens because carbon no longer has access to
@c DMUseScreenPrefs(), an undocumented function that changed the video
mode to the system default by using the system's "scrn" resource.
