1654 that had the most pixels counted under this scheme.
1656 this assumes that monitors earlier in the list are more desirable to be
1657 considered the search area's monitor. we try the configured primary
1658 monitor first, so it gets the highest preference.
1660 if we have counted an area A, then we want to subtract the intersection
1661 of A with the area on future monitors.
1662 but now consider if we count an area B that intersects A. we want to
1663 subtract the area B from that counted on future monitors, but not
1664 subtract the intersection of A and B twice! so we would add the
1665 intersection of A and B back, to account for it being subtracted both
1668 this is the idea behind the algorithm. we always subtract the full area
1669 for monitor M intersected with the search area. we'll call that AREA.
1670 but then we go through the list |counted| and for each rectangle in
1671 the list that is being subtracted from future monitors, we insert a
1672 request to add back the intersection of the subtracted rect with AREA.
1673 vice versa for a rect in |counted| that is getting added back.
