Someone was mentioning that clipping and scrolling could be slow on 
large lists because the scrollpanes still redraw all their internal 
morphs, and then just clip down...

Well, the morphs themselves have obscene, Morphic's layout has 
definitely improved, buut, there are some insane internals...

List item morphs, for example, have their rightmost xbounds at 9999!

And this supposedly set from somewhere inside when they recompute their 
bounds. Shouldn't a list item set it's right bounds at the edge of 
morph that contains it?

I'm trying to track down where this weirdness comes from...
