all (GUI):
- wxMenu(Bar)::Insert() and Remove() functions for dynamic menu menagament
+- wxToolBar supports arbitrary controls (not only buttons) and can be
+ dynamically changed (Delete/Insert functions)
+- wxDC::DrawRotatedText() (contributed by Hans-Joachim Baader, limited to
+ +/-90 degrees for now - contributions to improve it are welcome!)
wxMSW:
- wxTreeCtrl::IsVisible() bug fixed (thanks to Gary Chessun)
- tooltips work with wxRadioBox
-- arbitrary controls (and not only buttons) can be put into a toolbar
