compositor: blend with multiple threads

Increases the throughput of compositing by using more CPU cycles across
multiple threads.  Simple cases (the output contains one pixel from at
most one input) can have up to a 70% increase in throughput.  Not so
simple cases are limited by the region with the most number of
composite operations.
