  15 /*
  16    wxRenderer class is used to draw all wxWidgets controls. This is an ABC and
  17    the look of the application is determined by the concrete derivation of
  18    wxRenderer used in the program.
  19
  20    It also contains a few static methods which may be used by the concrete
  21    renderers and provide the functionality which is often similar or identical
  22    in all renderers (using inheritance here would be more restrictive as the
  23    given concrete renderer may need an arbitrary subset of the base class
  24    methods).
  25
  26    Finally note that wxRenderer supersedes wxRendererNative in wxUniv build and
  27    includes the latters functionality (which it may delegate to the generic
  28    implementation of the latter or reimplement itself).
