Make Alt-Tab highlight iconified items (in the tasklist) too

Browse Source 
Change the "overlay" actor to be a group of 4 actors that we can
rearrange so as to have a hole in the middle (to cover up the whole
screen except for the highlighted icon). For non-iconified windows, we
still highlight them the old way (raising them above the overlay),
because we don't want square highlights around shaped windows.
