 Test case

+Did some testing. The StatusBar code is absolutely ok. 
+It is the speed of the drawing methods in Graphics that hurts the
+StatusBar performance (aka cairo).
+If you comment
+dc.DrawString (text, panel.Parent.Font, br_forecolor, r, string_format);
+in ThemeWin32Classic.DrawStatusBarPanel it saves about 9 seconds for
+the test app on my system.
+Commenting the DrawLine code in CPDrawBorder3D saves another 7 seconds
+ and finally commenting CPDrawSizeGrip and the test app needs only 1.2
+seconds to run the loop.
+Oh cairo....
