Elijah Newren 703f58cdf7 Make the workspace switcher work with dual-head (non-xinerama) setups. 
2005-12-27  Elijah Newren  <newren@gmail.com>

	Make the workspace switcher work with dual-head (non-xinerama)
	setups.  Fixes #319423.

	* src/display.c (meta_display_open, event_callback,
	  meta_display_focus_the_no_focus_window):
	* src/display.h (struct MetaDisplay,
	  meta_display_focus_the_no_focus_window):
	* src/keybindings.c (primary_modifier_still_pressed):
	* src/screen.c (meta_screen_new):
	* src/screen.h (struct MetaScreen):
	* src/window.c (meta_window_new_with_attrs, meta_window_show):
	* src/workspace.c (meta_workspace_focus_default_window):
	Replace display->no_focus_window with a no_focus_window for each
	screen.

	* src/display.[ch] (meta_display_xwindow_is_a_no_focus_window,
	  event_callback):
	* src/window.c (meta_window_new_with_attrs):
	New utility function, meta_display_xwindow_is_a_no_focus_window(),
	for checking if the given xwindow is a no_focus_window for one of
	the screens.
