Detailed Description

Priority task dispatcher for zone fills - we want to do the biggest ones first.

On average, sorting the largest zones first is slightly faster (5-10%) on large boards.

However, if you allow the large zones to be assigned at random, as they basically will be if they are handled later in the process, there's a chance the very biggest zones will end up consecutive in the same thread which could be a substantial penalty.

Call this to execute the task on all items in aItems, using the thread pool and dispatching the tasks in order of descending priority as determined by comparePriority() implemented by the derived class.

This method blocks until all tasks are complete, and re-throws any exceptions thrown by the tasks.
