Hi all,

in pcb-rnd I'm trying to move items from globalconst.h to user 
configuration. I bumped into the two settings mentioned in the subject and 
I can't figure what they really mean. I found some discussion in the 
mailing list archives and some references in the changelog, but no place 
that explains what exactly we use these for. Can anyone enlighten me?

Also, why is it called GROUNDPLANEFRAME and not only PLANEFRAME (or even 
POLYFRAME)? The code doesn't seem to care if it's dealing with a gnd 
plane or not.

It's especially interesting how the .y file adds 2*MASKFRAME to the 
thickness of vias on load, while WriteViaData() doesn't subtract the same 
value on save. If I do load-save cycles on a pcb file, why don't I see 
via sizes climbing up?

TIA,

Igor2
