fn seeds_within(
drawing: &Drawing<'_>,
seeding: &Seeding<'_>,
within: Region,
) -> Vec<Point>Expand description
Seed points for a lattice covering within, and no others.
Gathered per lattice rather than once per pass: a commit that straightens every leg builds no lattice at all, and gathering 30,000 points for one that is never built was ~8 ms of every commit. Points outside the bounds are dropped here because the lattice would drop them anyway.
