lib2geom, new recipe (#12644)

this is usually part of Inkscape, but using the included one
in Inkscape causes some conflict

+SUMMARY="Easy to use 2D geometry library in C++"
+DESCRIPTION="2Geom is a C++ 2D geometry library geared towards robust processing of computational \
+geometry data associated with vector graphics. The primary design consideration is ease of use \
+and clarity. It is dual-licensed under LGPL 2.1 and MPL 1.1.
+
+The library is descended from a set of geometric routines present in Inkscape, a vector graphics \
+editor based around the Scalable Vector Graphics format, the most widespread vector graphics \
+interchange format on the Web and a W3C Recommendation. Due to this legacy, not all parts of the \
+API form a coherent whole (yet).
+
+Rendering is outside the scope of this library, and it is assumed something like libcairo or \
+similar is employed for this. 2geom concentrates on higher level algorithms and geometric \
+computations."
