I'm a novice to the pcb code base, and I couldn't find much developer

little help though: the pcb code base is too large for me to grok all

have to modify to allow this?
Actualy, there already is a patch.
It can be found here: https://bugs.launchpad.net/pcb/+bug/699495
This patch has some issues as mentioned in the bug report, but it should
be usable.
I am willing to fix and extend the patch, but I do have exams period(or
how is the english word for it) :-(
I should be on that issue in few weeks(like 2-3).
I've been looking at some brokenness with our normal thermal shape
generation recently, so if I get a chance I could look at your patch -
and possibly work from it.
The main problem I have is not code, but deciding what such geometry
needs to look like it and how to specify it. Whatever we decide we have
to live with, as we can't go changing geometry on users with existing
boards.
That is the problem I'm hitting now. Harry's clipper branch (a long time
ago) without comment, changed the thermal generation formulas in (IMO, a
retrograde way). I can't change it back (or fix the geometry
calculation) for fear of possibly breaking all the users who have made
boards since then.
