Add a configuration option to ignore Decoration Hints from GTK-based application
As reported by Nerijus Baliunas and Paul Jakma, the GNOME application,
which use the GTK toolkit, are asking to have no window decoration. This
can be solved by editing the window's attributes in Window Maker, but this
can be tedious when there are many GNOME application used.
This patch adds a configuration option: Window Maker tries to detect for
GTK-based windows and in this case ignore the decoration hints that were
provided by the application.
