wxMotif:
--------
-- wxNotebook and property list frame do not appear properly when
- first shown.
- Workaround: resize the window (manually or programmatically) to
- make the window appear.
- This also happens with other windows, e.g. the sizer
- dialog in the layout sample.
-
-- wxSashWindow borders aren't repainted properly if the sashtest
- sample is exposed (after being under another window).
-
- If a popup wxMenu is destroyed after its parent window has been
destroyed, we get the message "Object XXX does not have windowed
ancestor".
- Setting the size of a hidden window may show that window.
+- Motif-specific wxImage functions not yet implemented.
