13 Renderers are used in wxWindows for two similar but different things:
14 (a) wxUniversal uses them to draw everything, i.e. all the control
15 (b) all the native ports use them to draw generic controls only
17 wxUniversal needs more functionality than what is included in the base class
18 as it needs to draw stuff like scrollbars which are never going to be
19 generic. So we put the bare minimum needed by the native ports here and the
20 full wxRenderer class is declared in wx/univ/renderer.h and is only used by
21 wxUniveral (although note that native ports can load wxRenderer objects from
22 theme DLLs and use them as wxRendererNative ones, of course).
