This change defers event routing from the time the event is queued until
the time Events is called. This allows a future change to execute
commands immediately and to react to event order changes during a frame.

Replace the per-event event queues with a single queue of events, each
marked with the target tag. This change is a prerequisite for lazy event
delivery.
