Per-monitor DPI awareness
A laptop at 150% scaling with an external monitor at 100% is the ordinary case now, not an edge case. An application that is not per-monitor DPI aware becomes blurry on one of them, because Windows scales its output as a bitmap.
DeskDrawer declares PerMonitorV2 awareness, so it is told about DPI changes and redraws at the correct scale — including when a board is dragged from one monitor to the other mid-gesture.
