In my app I have a NSTextView which is used as a temporary editor,
being attached to another view while it edits some text, then removed
when I'm done. This is set up to size vertically as the text is
entered, and it does. While it's growing, all is well, but if it
shrinks by one or more lines, the leftover lines are not updated,
leaving them visible until something draws over them.
What's a good way to ensure that the text view gets updated properly
at all times? I can't use textDidChange: because it's too late - the
bounds/frame of the view has already been changed by that time. There
must be something simple I'm just not seeing.
