Resizing
Resize handles on any side or corner, the edge that stays put, and the limits a resize stops at.
A GridLayout.ResizeHandle is a side or corner its item is resized from. Pull it and the item
grows or shrinks by whole columns and rows, the opposite edge staying put, and what it grows into
is pushed past its new edge.
<GridLayout.ResizeHandle side="bottom-end" aria-label={`Resize ${name}`} className="corner" />The sides are logical: top, bottom, start, end, and the corners top-start, top-end,
bottom-start, bottom-end. In right-to-left, start is the right edge.
Limits
A resize stops at the item's minW, maxW, minH and maxH, at the grid's columns and at
maxRows, whichever side pulls. A handle renders nothing while its item cannot be resized.
A handle needs a box
A handle has no size or place of its own: give it both, or there is nothing to press. Its
touch-action is set for you, so a touch on it resizes rather than scrolls.
