The main issue is the ability to render complex layerings at high zoom (13 or 14 is where the distinctions are generally visible). The discussion of performance is to demonstrate...

This is also apparently a duplicate of a Mapbox issue: mapbox/mapbox-gl-js#1349

I'll mock up some illustrations which will hopefully better express the problem.

Suppose we have a stacked interchange as follows, with 4 different levels of bridges. In other words, the lowest level (layer=1) is a motorway viaduct, and there are additional bridges...

The problem is that I have to anticipate the highest possible value of `layer` that might exist in in the data, let's call that **N**. I then have to replicate...

The problem is that I don't know what **N** is. Replication is easy, it's just a [for loop](https://github.com/ZeLonewolf/openstreetmap-americana/blob/9e85aa4b1327b878e3f0d0bb0e89d12290d48353/src/layer/rail.js#L436-L450)! When we implemented this originally, we crawled the map looking for worst-case...
