	* gdk/linux-fb/gdkdrawable-fb2.c:
	For optization, add an full_shapes argument to gdk_fb_clip_region.
	If this is false, only the cliprects of the shapes are used.

	* gdk/linux-fb/gdkprivate-fb.h:
	Export gdk_fb_window_peek_shape.
	Add full_shapes to gdk_fb_clip_region.

	* gdk/linux-fb/gdkwindow-fb.c (gdk_fb_window_move_resize):
	When moving a window, don't clear everything under the it, just the
	root window. Makes stuff faster and flash less.
	(gdk_window_get_pointer): Correctly handle offseted shapes, due to
	USE_CHILD_SHAPE. (gdk_fb_window_peek_shape): Return the correct
	offset of the shape.
