=> note-output-record-child-changed record child mode old-position old-bounding-rectangle stream
&optional erases moves draws erase-overlapping move-overlapping &key check-overlapping [Generic Function]
note-output-record-child-changed is called after an output history has had changes made
to it, but before any of the new output has been displayed. It will call propagate-output-
record-changes-p to determine if the parent output record should be notified, and if so, will
call propagate-output-record-changes to create an updated difference set. If no changes need
to be propagated to the parent output record, then note-output-record-child-changed will
call incremental-redisplay in order display the difference set.

mode is one of :delete, :add, :change, :move, or :none

old-position and old-bounding-rectangle describe where child was before it was moved.

check-overlapping is as for compute-difference-set.

=> propagate-output-record-changes-p record child mode old-position old-bounding-rectangle [Generic Function]
propagate-output-record-changes-p is a predicate that returns true if the change made to
the child will cause record to be redisplayed in any way. Otherwise, it returns false. mode is one
of :delete, :add, :change, :move, or :none.
