Umm, why not use the parent cell's ID as the flobpath? We don't want to
waste space for *both* a flobpath and a parent cell. Another way is of
course to get rid of flobpaths. I don't know.

Now, the big question is: how much hit to performance is this when the
features are not used? How efficient can it be made? The point is that we
want to be able to slap thousands of flobs to the screen quickly and
interpolate between them. 

At one point I had planned to make FlobSets hierarchical so that a FlobSet
is also a Flob that can be painted on the screen. It might be faster that
way...

This sounds reasonable.

Combining this with some way of showing beams, i.e. showing that two flobs
are in fact from the same cell would be interesting.
