The Circle fill strategy's stripe layouts (FillEndOdd, FillEndEven) now try
switching from staggered to straight stripes, a diameter apart over the last
staggered stripe, at every stripe, all staggered and all straight included,
and keep the switch that places the most; a tie stays staggered. A 9" circle
on a 60x120 sheet at 0.2 spacing now fills 89 (five staggered rows, two
straight) instead of 88.

FillEndOdd and FillEndEven had no production callers, so round parts
only got stripe layouts. A Circle strategy now runs them in the fill
pipeline: 8in circles on a 60x120 go from 98 to 112.
