A changed form (Alt + scroll on the radius) is prepared 150 ms after it last
changed, the sphere drawn meanwhile; a region of more than 1000 nodes is not
previewed and moves on release.

With the form open a drag on the mesh grabs the node under the press and
moves it in the screen plane; Alt + scroll sizes the radius. The view draws
the original edges as a ghost under the moved ones, coloured by how each
element's scaled Jacobian changed, and the sphere; the form shows the region's
numbers live. Release runs mesh.node.move (one undo step), Esc cancels.
