15 is an empirical number from a long time ago. More rectangles can 
increase the number of times a given morph may be asked to draw in a 
single update cycle. Fewer rectangles increases the chances for a morph 
to be included when it hasn't changed itself. It's easy enough to change 
the 15 and to limit the clock display. It's also pretty easy to capture 
some data in PasteUpMorph>>privateOuterDisplayWorld to see what the 
effects are. Might be a big win or something less amazing.

Cheers,
Bob
