The only way I can see to truly have stable scroll-bar size is to base
the size calculation on displayed pixels (lines are not necessarily a
constant height, so the number of displayed lines is not a fixed
proportion of total lines in the document).
I'm curious how _any_ program manages to do this calculation in a
reasonable amount of time; do they really lay-out the _entire_
document ahead of time? Do they use some sort of heuristic instead?
What happens when the heuristic fails?
