StateMapView

Remarks

⚠ Drawn rather than built out of elements, for NodeMinimap's reason. A state is a rounded box with a label and an arrow is a line with a head; as elements they would be a style node, a layout box and a rebind each, for a picture whose only interactions are click and drag. Hit-testing two dozen rectangles is cheaper than laying out two dozen elements, and it is the whole of what this control needs.

⚠ The drag commits once, on release. Moving a state writes its position into the document, and a command per pointer-move would be forty undo entries for one drag — so the box follows the pointer in this control's own field and the document is told when the button comes up. That is the same bargain Timeline makes with its keys.
