on-resize (augmentable only) in pasteboard%

Called before a snip is resized by 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.

Note that a snip calls resized, not this method, to notify the pasteboard that the snip resized itself.
