	Patch from Aidan Delaney to make sure that icons in the alt-tab
	popup are dimmed for all hidden windows, not just minimized ones.
	Fixes #168455.

	* src/screen.c: (meta_screen_ensure_tab_popup): make use
	meta_window_showing_on_its_workspace() instead of just checking if
	the window is minimized.
