Please note that callback functions that go back to python must lock
the python GIL effectively creating a bottleneck if there are many
such python callbacks.

Also, the current implementation signals the GUI when there is an
image ready to display. This causes a refresh call that in turns
grabs the pixel data, displays it, then releases the engine to
continue. Without a profiler, I couldn't tell you exactly where the
bottlenecks are, but I hope this helps.
