Title: Fix build error caused by nonconst reference in comparison lambda

On Linux, I get the following build error on master.
```
2D/path_renderer.cpp:112:103: note: no known conversion for argument 1 from 'const clan::PathScanlineEdge' to 'clan::PathScanlineEdge&'
```

This small change fixes that.
