//! The map_editor renders and lets you edit RawMaps, which are a format in between OSM and the
//! full Map. It's useful for debugging maps imported from OSM, and for drawing synthetic maps for
//! testing.
//!
//! TODO It's a bit unmaintained / rarely used. Two big problems using it:
//! - Intersection geometry isn't recalculated constantly as changes are made
//! - The app will run out of GPU memory up-front on huge maps, because of storing objects for
//!   every road and intersections
