Just for reference and maybe other ideas:
https://bugs.launchpad.net/kicad/+bug/593972

I just tried applying your patch, but it will segfault when I try to
apply the teardrops. It was a previously routed design I tested. I
also tried the coldfire demo board. Attached is a backtrace.

> The patch attached adds simple teardrops implementation. All the teardrops
> are "painted" by tracks and I mark the tracks with FLAG1 in order to
> differentiate them from regular tracks. This flag is not used anywhere in
> the sources so I took the liberty to use it for my purpose. I hope nobody
> will object. This is definitely not the most elegant solution but it works.

> This implementation should not be considered as a final work and it has a
> number of limitations:
>
> 1. I can not figure out a clean solution which would allow me to delete a
> single teardrop from inside the code. Currently, the user have the options
> to either remove all the tracks composing a teardrop manually or use the
> batch processing to remove all the teardrops from the board. I guess the
> best option would be to link teardrops to parent tracks but this requires
> deeper modifications to the sources.
>
> 2. Adding teardrops to medium or big size boards takes pretty much time. I
> add teardrops to the board calling BOARD::Add() and KIGFX::VIEW::Add() for
> every single track composing teardrop and profiler (callgrind) says that
> those are two most expensive operations in my code. Are there any ways of
> speeding up the process?

> I will continue to work on the code but may be with less effort. Your advice
> and criticism are highly welcome. I hope this patch will be useful.
