Usually GUI update actions are done in a single ActionGroup, as you
have, i.e. by default they execute in the order they are put in the
ActionGroup.  In fact, that needn't be the default, and often there is
an important ordering to the GUI update actions.  For example, you
have an eraseRaster before the display.  (In other cases, when using
ActionGroup, the intent is to communicate the fact that the 
actions are logically concurrent, so that Swarm could (conceivably) 
physically parallelize the actions.)  

In the former case, you're better off making a single update method that
calls the GUI update methods in the required order and scheduling it
with at:createActionTo:message:.  Then it is simply a matter of calling
the update method at the end of buildObjects.
