Add a fallback for unconverted backends

Browse Source 
If the monitor vfuncs are not implemented in a display class,
fall back to providing a single monitor object representing
the entire screen. This is not meant to be 'good enough', it
is just to provide some implementation until the last backends
implement the monitor vfuncs. When that is the case, the
fallback should be removed.
