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