Import the code (only) from the GEGL soc-2011-seamless-clone branch

The poly2tri-c code was developped inside the GEGL repository as part of the
Google Summer of Code 2011 project. It is time to seperate the repositories and
to make poly2tri-c an independent library.
The code checked in in this commit is from commit 6ae8521387 of GEGL.
