Abstract parallel process, which performs a certain task (to be defined by the subclass) on the pixels of an image where work on adjacent pixels is independent. For preview purposes, a spiraling pattern of square pixel blocks is generated.

Generate a piece of work.
Takes a pre-allocated WorkUnit instance of the appropriate sub-type and size (as specified by ParallelProcess::getWorkUnitName()) and fills it with the appropriate content. Returns ESuccess on success and EFailure or EPause when no more work is left – in that case, the work unit will be ignored and the process completed (EFailure) or temporarily paused (EPause). When EPause was used, resubmission via Scheduler::schedule() will be required once more work is available. In some cases, it is useful to distribute 'nearby' pieces of work to the same processor – the worker parameter can be used to implement this. This function should run as quickly as possible, since it will be executed while the scheduler mutex is held. A thrown exception will lead to the termination of the parallel process.
