-// Revision 1.14 2004/09/28 18:44:25 pbartok
-// - Streamlined Theme interfaces:
-// * Each DrawXXX method for a control now is passed the object for the
-// control to be drawn in order to allow accessing any state the theme
-// might require
-//
-// * ControlPaint methods for the theme now have a CP prefix to avoid
-// name clashes with the Draw methods for controls
-//
-// * Every control now retrieves it's DefaultSize from the current theme
-//
