/*
   Renderers are used in wxWidgets for two similar but different things:
    (a) wxUniversal uses them to draw everything, i.e. all the control
    (b) all the native ports use them to draw generic controls only

   wxUniversal needs more functionality than what is included in the base class
   as it needs to draw stuff like scrollbars which are never going to be
   generic. So we put the bare minimum needed by the native ports here and the
   full wxRenderer class is declared in wx/univ/renderer.h and is only used by
   wxUniveral (although note that native ports can load wxRenderer objects from
   theme DLLs and use them as wxRendererNative ones, of course).
