	Ah!  One of the lesser-known new functions in 1.2 Intuition is the
call InstallClipRegion().  There is (I think) an example on a fish disk
done by either RJ or Jim Mackraz of this, and it is documented in the
1.2 AutoDocs (mentioned on page 68 of the Enhancer booklet).  This does
EXACTLY what you are looking for, without the GZZ overhead (you can even get
quite fancy with it).
