Struct VisvalingamWhyattPreserve 

pub struct VisvalingamWhyattPreserve;

Topology-preserving Visvalingam–Whyatt line simplification.

Uses the same area ranking as VisvalingamWhyatt, and applies the Davies refinement when removing a vertex would introduce a self-intersection: the preceding retained vertex is removed next so the transient crossing is eliminated. The implementation uses an allocation-only quadratic scan, keeping the strategy available in no_std builds.
