Apply blackc@speakeasy.net patch, bug #83940, to do mini-workspaces

2002-07-06  Havoc Pennington  <hp@pobox.com>

        Apply blackc@speakeasy.net patch, bug #83940, to do
	mini-workspaces similar to the pager, when switching
	spaces.

	* src/window.c (update_net_wm_state): actually fill in
	wm_state_skip_taskbar, wm_state_skip_pager flags

	* src/tabpopup.c: support drawing a mini-workspace similar to the
	one the pager draws.

	* src/stack.c (meta_stack_list_windows): new function to list
	the windows in stacking order

	* src/screen.c (meta_screen_ensure_workspace_popup): don't pass in
	the ugly default app icon for workspaces

	* src/display.c (event_callback): fix from blackc@speakeasy.net
	to avoid dereferencing a NULL grab window.
