Can we figure out a better name for these than EventMask's.  We use that name also in the Event/Listener/Broadcaster interaction, so having it used for a similar but slightly different purpose here is going to be confusing.

How about calling these Triggers?  That goes along with saying the callbacks "fire" when  something happens...
