Make pitchscreen absolute point mode compatible.
It's very similar to how it's controlled in the grid mode (in fact, it resembles this mode and they're compatible).
We could've forced the grid mode, but the viewport layout needed fixing for the addional icons anyway, and this way it doesn't
break with an ui viewport.
