With regards to the Morphic event improvement now going on at SqC,
just one observation:

>From a message tally, it's apparent that a lot of the work being
done in Morphic is just finding the world under the cursor.

For instance, in a typical session, Morphic spent 14% of its time
looking for worlds in PluggableTextMorphs.

An obvious optimization here would be to maintain a global collection
of worlds that could be queried, instead of traversing the entire
collection of Morphs depth-first.

This could help power consumption considerably in PDA versions,
along with getting the event VM to work right.
