after-resize

Called after a given snip is resized (and after the display is refreshed; use on-resize and begin-edit-sequence to avoid extra refreshes when after-resize modifies the editor), or after an unsuccessful resize attempt was made

See also can-resize? and on-edit-sequence.

No internals locks are set when this method is called.

      snip : snip% object
