It's possible that some window managers don't honor dynamic changes
(changes after you show the window). gdk_window_set_decorations
(window, 0) works pretty reliably, but using any other arg to
set_decorations or changing it after showing the window is kind of
window-manager-dependent.

The hints used for gdk_window_set_decorations() are the old Motif/mwm
hints, not something GTK invented, but they are pretty poorly
documented (i.e. not documented at all), so it's hard to say what
window managers "should" do. It's not in any spec.
