History
Dustin Carlino 6119042b4f Reorder points when converting a PolyLine to a Polygon, so that the 
result is usually a Ring. This gets lanes to render in the GeoJSON
export. #440

Ideally all Polygons would be expressed as an outer Ring and some
optional inner Rings. There are a few cases where this is hard, and we
instead just rely on the triangulation for rendering and point
containment and give up on GeoJSON export.

Not regenerating all maps yet -- zero screenshot diff, the map file does
change, but not sure how.

geom

This crate contains primitive types used by A/B Street. It's unclear if other apps will have any use for this crate. In some cases, geom just wraps much more polished APIs, like rust-geo. In others, it has its own geometric algorithms, but they likely have many bugs and make use-case-driven assumptions. So, be warned if you use this.

Contents

Many of the types are geometric: Pt2D, Ring, Distance, Line, InfiniteLine, FindClosest, Circle, Angle, LonLat, Bounds, GPSBounds, PolyLine, Polygon, Triangle.

Some involve time: Time, Duration, Speed.

And there's also a Percent wrapper and a Histogram.
