after-resize (augmentable only) in pasteboard%

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.

• (send a-pasteboard after-resize snip w h resized?) -> void
     snip : snip% object
     w : non-negative real number
     h : non-negative real number
     resized? : boolean

  If resized? is not #f, the snip was successfully resized.
