// This object is the guts of the whole game. It is like a central clearing
// house... it renders all the peices within itself. Rather than having lots
// of independent views that do theire rendering all throughout the game, this
// view ties together a lot of player/ghost objects and has them render
// themselves inside of itself. This makes the drawing a bit more efficient
// and allows allows easy programmatic control of which order things get drawn
// in. Since the images all use transparency, etc., this order is very
// important. The two main methods in here are the autoUpdate: method, which
// is a giant state machine that handles the logic of the game, and the
// updateSelf:: method that updates the screen from one animation frame to the
// next. drawSelf:: is a less complex version of updateSelf:: because it
// always renders the whole view, not just the things which have changed since
// the last update. By having two different methods, drawing is sped up at
// the sacrifice of code clarity. (Having two different rendering methods
// gives better speed, but code complexity is nasty and the difficulty of
// keeping both methods in sync so that they give identical results make for
// a lot of work.) I haven't yet found a good way to simplify the rendering
// engine without slowing it down...if you have any suggestions, I would like
// to hear them of course, but I've already tried quite a few things.
