gEDA-user: PolyStitch plugin

[DJ Delorie <dj@xxxxxxxxxxx>]

I needed to do some logos, so everyone gets a logo tool :-)

PolyStitch is a PCB plugin to fix the output of pstoedit's "pcbfill"
output, when you have text with holes in it (like the letter "d").
Pstoedit makes two polygons, one for the outside and one for the hole,
but what you really want in PCB is one polygon, so that the hole is
not filled.

This plugin, used when the crosshair is over the inner polygon,
stitches the two polygons together such that the area inside the inner
polygon becomes "outside" the resulting polygon.  Basically, it cuts
the shape at the narrowest spot and stitches the point lists together.

It can also be used to cut holes in a ground plane, by drawing the
hole as a separate polygon then stitching it to the plane's polygon.
