[PD] Highlight modified abstraction instances with red

[Luke Iannini (pd)]

Hallo all,
Just wanted to post an idea...
It would be great if Pd highligted modified abstractions in red in
their parent patch (that is, the one pixel bounding box and text.
When I've modified one of a bunch of abstractions in a parent and
close it without saving, I have to open each one to see if it was the
one I modified.

Another thing I've been thinking about is an integrated method to view
diffed patches (most especially when resolving an SVN conflict)...
something like OS X's FileMerge for Pd.

Ok, there are my PitS ideas, in case anyone wants to write them before
I get around to it :).
