Indeed a few things are easier to do, so there is definitely progress
in this area. But I've also noticed sometimes problems with microscopic
examination of the result. 

I'm designing right now with PCB some very high resolution circuit on alumina, 
where design rules can be down to 10µm/0.4mil minimal width and spacing, 
although I stay at a more reasonable 50µm/2mil for my first thin film circuit. 

Anyway, I've always been able to fix the small issues I've encountered, 
so it's not a serious problem.

I also had the impression that snapping on arc ends was problematic,
but I can't reproduce the problem right now.

Well, it's very useful when you wnat to modify the shape of a polygon, which
is very frequent when putting the finishing touches to microwave circuits.

I have bisected the problem to commit b59ab044afe3ac362f8cb4da10ea410280b4323a,
probably src/insert.c, but I'm busy with other things and can't try to tackle
the issue right now (I might find some time over the week-end).
