the sprites will be drawn batched together. This improves performance by giving the
GPU a nice chunk of work to do in a minimal number of API calls, so we don't need
to keep going through the API and driver layers continuously, wasting time. To do
this, we need to let the batch know when it should begin and when we're done issu-
ing the commands, so that it can do some work, batch everything together, and draw
to the screen.
