focus top window when switching to a new workspace

Browse Source 
2002-01-03  Havoc Pennington  <hp@pobox.com>

	* src/workspace.c (meta_workspace_activate): focus top window when
	switching to a new workspace

	* src/util.c (meta_topic): start putting verbose output in
	categories

	* src/window.c (meta_window_shade): focus frame after we queue
	the calc_showing so the maps/unmaps have already happened.

	* src/display.c (meta_display_get_current_time): add the "get time
	of current event" function and call it occasionally.

	* src/window.c (meta_window_free): if we have focus, call
	meta_screen_focus_top_window().
	(meta_window_minimize): ditto
	(meta_window_delete): ditto

	* src/screen.c (meta_screen_ensure_tab_popup): fix memory leak -
	didn't free tab list
	(meta_screen_focus_top_window): new function to use when we unmap
	or unmanage a focused window

	* src/stack.c (meta_stack_get_default_focus_window): function used
	in meta_screen_focus_top_window
