/**
   @name Stub backend functions

   Implementations of stub backend functions which do nothing and always return
   success.  These do not make for a usable backend on their own since the
   platform implementation would fail to create a window, but are useful for
   other backends to reuse since not all need non-trivial implementations of
   every backend function.
