	* gtk/gtkwindow-decorate.[hc]:
	* gtk/Makefile.am:
	New files. Contains an implementation of a minimal WM for
	linux-fb.

	* gtk/gtkwindow.h:
	Add the possibility for GtkWindows to specify a frame. This
	is used for the window decoration code, but could concievably
	be used for X programs too (xmms style windows).
	GtkWindow->frame is the toplevel window if the window is framed.
	The signal frame_event gets all events that are targeted to
	GtkWindow->frame.
	(_gtk_window_constrain_size): Exported for usage by gtkwindow-decorate.c.

	* gtk/gtkwindow.c:
	Implement gtk_window_set_has_frame and gtk_window_set_frame_dimensions.
	Call out to gtkwindow-decorate.c for WM support in linx-fb.
