bevy 2d line
Bevy port of https://github.com/mattdesl/three-line-2d Polylines in a vertex shader; plays nice with projection scale, z-index; supports vertex colors. Does not support picking!
Moving thousands of line endpoints every frame will be slow, because the mesh needs rebuilt when the lines are moved.
Lazily maintained at best!
