on-resize

Called before a snip is resized in the editor, after can-resize? is called to verify that the resize is allowed. The after-resize method is guaranteed to be called after the resize has completed.

The editor is internally locked for writing when this method is called (see also Locks). Use after-resize to modify the editor, if necessary.
