Polyptych - interactive unwrapper

Polyptych currently lives in the Laidout source. At some point,
the things here will most likely be separated from Laidout into its own
project, and Laidout will use libraries from that project.

You can grab the code with the following. The actual standalone is then in laidout/src/polyptych.
git clone https://github.com/Laidout/laidout.git
You will need the most recent development version of the Laxkit, and a few other things:
apt-get install libgraphicsmagick++1-dev mesa-common-dev libglu1-mesa-dev libftgl-dev
Then to compile:
make polyptych
make spheretocube
make spheretopoly
make convertahedron
Or on debian based systems:
dpkg-buildpackage -rfakeroot
