Its filtering seems a little more powerful, e.g. for automatically 
generaring minimaps from larger background tiles. Using blurs, etc for 
effects is also interesting, but I suspect that these may end up being 
too slow...

I'd like to see this - there would be a number of advantages to doing it 
this way rather than building up large chunks of sound to feed to the mixer.

Can anyone point me to a good example of a fast scrolling background 
(full-screen or nearly full-screen)?
