resizeBox

The default resize for a box-shaped shape.

Handles the three things every box shape gets wrong when it writes this itself: a negative scale (dragging a handle past the opposite edge, which should flip the box rather than give it a negative width), the position change that a flip implies, and clamping to a minimum size without letting the box drift while it is clamped.

Returns the props to merge into the shape, so a util can post-process the result: return { ...resizeBox(shape, info), props: { ...} }.
