This is driving me crazy, searching for some answers on this one.

Zoom in on the snowboard and drag it around, it appears the low-res  
image is updated with hi-res patches on the fly.

Is this a function tied to the bitmap object… or  
did they write some fancy code to pull in and assemble a sliced up image, and  
then replace the low-res slices on the fly.

thanks for any insight.
