Moving this to a centrally controlled location so it's easier to migrate to choreographer. Also turn the stupid int into a bool.
It looks like whoever wrote this just kept adding draw calls until it worked. For some reason if I removed the call from `APP_CMD_INIT_WINDOW` (which really shouldn't have needed to render), or added an `if (!animating)` early exist to engine_draw_frame, it would prevent the app from *ever* rendering. I never figured out why, but in any case the most important call is the one that was missing: the one in `APP_CMD_GAINED_FOCUS`. That's why the rendering wouldn't start until you tapped the screen. I added that and now all the calls that appear superfluous in fact are.
