The erasing isn't needed in that case since the Value2dDisplay draws
over all the old values (and then the bugs are drawn).  If you don't
want a Value2dDisplay, you can add this line before scheduling the
other display methods:

  [displayActions createActionTo: worldRaster message: M(erase)];

I don't see a need for the second Object2dDisplay.  You should be able
to put heterogeneous agents in a bug list.
