Right now, we are trying to just exactly match the design rules.
But this means that single traces go between pads very close on one side.
We should try to center this. Rough ideas
springiness around the edges. It reaches out to the next solid thing and tries to center itself. But only if we 'hit' something within 2x (3x ?) the current position.
maybe just do it if we notice that it wouldn't be possible to fit another trace there. E.g. it it was not possible to put another trace of the current size between two pads, then the single trace we put through there should be centered.
