Struct VisvalingamWhyatt 

pub struct VisvalingamWhyatt;

Visvalingam–Whyatt area-ranked line simplification.

Repeatedly removes the interior vertex with the smallest adjacent-triangle area while that area is at most the tolerance supplied to SimplifyStrategy::simplify. Endpoints are always retained.

Implements the method from Visvalingam and Whyatt, “Line Generalisation by Repeated Elimination of Points” (1993). Boost.Geometry has no equivalent strategy; this is an opt-in peer of DouglasPeucker.
