Disable Path Encoding

since 3.3.0

In order to preserve bandwidth the polyline/polygon path coordinates are encoded (default) with a lossy algorithm (i.e. some precision is lost - visible at high zoom levels). In cases where the highest precision is needed (e.g. when editing a polyline/polygon) this encoding can be disabled by setting pathEncoded="false" / polygon.setPathEncoded(false); - at the cost of increased network request and response sizes.
