`Static`recomputeDragScalePerMove

recomputeDragScalePerMove: boolean = true

When true (default), each window-level dragmove recomputes the canvas rect and renderer scale via getBoundingClientRect(). This makes drags survive mid-drag canvas resizes, DPR/monitor changes, and CSS-zoom animations without the cursor and element drifting apart.

Set to false to skip the per-move rect lookup (cache scale once at dragstart). Saves a couple getBoundingClientRect() calls per pointermove — measurable only at very high move rates or with thousands of concurrent draggables.
