I agree. But what if one of your "userItems" is to be animated, in other words, 
what if you need it to be updated everytime through ModalDialog's event loop. 
Then you'd have to use the filter function. And if you're gonna use it anyway, 
you might as well draw the other items when you get an update event from the 
filter function. This updates all items even through a screen saver.
