QUESTION 1:
Why do this as "step 2.5"?  I'd think that Step 5 ("Distribute free
space proportional to the flex factors") would be the obvious place to
make this tweak. (just changing the ratio that we use, if the sum of the
flex-grow factors is < 1, but otherwise doing everything normally)

QUESTION 2:
Why exit the algorithm? I'd expect that we'd need to proceed with the
"Fix min/max violations" and continue cycling as appropriate.
Otherwise, we'd never discover min/max violations, and we'd end up with
elements sized too small or too large for those constraints.
(If instead we moved this logic to be in Step 5, as suggested above, and
dropped the "exit", then I think we'd honor the constraints correctly...)
