Forked from "Bullet Tracers" by kittah_khan: https://mods.factorio.com/mod/visual_tracers

The bullet tracer graphic and its associated animation are not mine. All credit for the original work goes to kittah_khan.

My version tracks bullets shot from each entity (turret/player/etc) and generates a new tracer every nth round (default 3 shots), rather than randomly.

This may have performance issues, since the mod tracks each individual bullet fired from every source.
