WaySimplifyFilter class
A filter that simplifies way geometries using the Douglas-Peucker algorithm.
This is a crucial performance optimization that reduces the number of vertices in a way while preserving its general shape. The level of simplification is determined by a maximum allowed deviation in pixels, which is converted to a geographical distance based on the current zoom level and latitude.

reduce(
Wayholder wayholder) → Wayholder -
Reduces the complexity of all ways within a
wayholder. -
reduceWayEnsureMax(
Waypath waypath) → Waypath -
