Ah, this one seems to be a trivial oversight on our part. In
awt_Toplevel.c in shellEH() ReparentNotify processing in the case of
OTHER_WM is entirely conditional on ifdef __linux__ and so frames got
some ridiculous insets (like 144 for bottom and right) and so swing
would obey and won't paint in those areas.

Removing the ifdef fixes this: e.g. SwingSet2 uses the whole frame.
ifdef __linux__ must die in WM related code!
