Add _NET_WM_ICON_GEOMETRY atom.

2001-08-05  Anders Carlsson  <andersca@gnu.org>

	* src/display.h, src/display.c: Add _NET_WM_ICON_GEOMETRY atom.

	* src/window.c (meta_window_calc_showing): See if the window has
	an icon geometry and show a morphing animation from the window's
	coordinates to the icon's coordinates.
	(meta_window_get_icon_geometry): New function that fetches a
	window's icon geometry.

	* src/Makefile.am: Add effects.[ch].

        * src/effects.c: New file with cool effects.
