Create a sparse array for monitor-geometry-changed

Browse Source 
It's possible to have only display N enabled without having all of the displays
before it. I experienced this a couple times with a windows guest where display
1 would show up before display 0 and we'd hit a warning that nth is not less
than nmonitors. So find the highest display ID and then create an array of that
size, leaving missing displays initialized to 0
