Escape during a Selection tool move or Alt-drag copy, a bounding-box
scale or rotation, a marquee, or a drag of a corner widget, a pie widget
or the brackets of type on a path did nothing, and the release then
applied the drag. Only a ruler guide, mirror axis or grid repeat drag
and the loaded text took Escape.
Escape in any of these drags now cancels it, the way Direct Selection
cancels its drags: the art returns to its state at the press, an
Alt-drag leaves no copy, no undo step is added, and the release does
nothing.
Outside a drag Escape works as before.
