Elijah Newren d8d77bd65b Focus the desktop when showing it. Fixes #159257. 
2004-12-19  Elijah Newren  <newren@gmail.com>

	Focus the desktop when showing it.  Fixes #159257.

	* src/display.c (event_callback): obtain a timestamp to pass to
	meta_screen_show_desktop

	* src/keybindings.c (handle_toggle_desktop): obtain a timestamp to
	pass to meta_screen_show_desktop

	* src/screen.c (meta_screen_show_desktop): add a timestamp
	parameter, get the most recently used window of type DESKTOP (if
	there is one) and focus it

	* src/screen.h (meta_screen_show_desktop): add a timestamp
	parameter
