  12 /*
  13    wxRenderer class is used to draw all wxWindows controls. This is an ABC and
  14    the look of the application is determined by the concrete derivation of
  15    wxRenderer used in the program.
  16
  17    It also contains a few static methods which may be used by the concrete
  18    renderers and provide the functionality which is often similar or identical
  19    in all renderers (using inheritance here would be more restrictive as the
  20    given concrete renderer may need an arbitrary subset of the base class
  21    methods)
