        Fix for the "mangles focus window when switching workspaces
	and using mouse focus" bug

	* src/stack.c (meta_stack_get_default_focus_window_at_point): new
	function

	* src/screen.c (meta_screen_focus_mouse_window): new function
	(meta_screen_focus_default_window): new function

	* src/workspace.c (meta_workspace_activate): use the
	new meta_screen_focus_default_window()

2003-01-17  Havoc Pennington  <hp@pobox.com>

	* src/window.c (meta_window_handle_mouse_grab_op_event): fix event
	compression code to use GDK algorithm suggested by Owen, should be
	more efficient.
