	* gdk/linux-fb/gdkdrawable-fb2.c (gdk_fb_clip_region): Take shaped
	windows in consideration when generating clip region.

	* gdk/linux-fb/gdkfb.h:
	Huge HACK. Added GDK_FB_USE_CHILD_SHAPE.

	* gdk/linux-fb/gdkprivate-fb.h:
	Add shape to GdkWindowFBDatat.
	exported gdk_fb_window_get_abs_shape().
	removed gdk_fb_draw_lines declaration.

	* gdk/linux-fb/gdkwindow-fb.c (gdk_window_impl_fb_init):
	Init shape to NULL. (gdk_fb_window_send_crossing_events): Don't
	send focus changes when there is a grabbed window.
	(gdk_window_get_pointer): Handle shaped windows.
	(gdk_fb_region_create_from_bitmap): Convert bitmap to region.
	(gdk_fb_window_peek_shape): Returns the shape for a window,
	handles GDK_FB_USE_CHILD_SHAPE.
	(gdk_fb_window_get_abs_shape): Returns the shape of the window,
	offseted to absolute positions. Handles GDK_FB_USE_CHILD_SHAPE.
	(gdk_window_shape_combine_mask): Implement.

	* gtk/gtkwindow-decorate.c:
	HACK! Set GDK_FB_USE_CHILD_SHAPE on window->frame to make sure
	setting the shape of a window makes the window transparent.
