/**
 * \file lpe-framework.h
 * \brief A framework for writing an Inkscape Live Path Effect toy.
 *
 * Instead of using the standard toy framework, one can use this LPE 
 * framework when creating an LPE for Inkscape. When new 2geom functions 
 * are required for the LPE, adding this functionality directly in Inkscape 
 * greatly increases compile times. Using this framework, one only has to
 * rebuild 2geom, which speeds up development considerably. (Think about
 * how much of Inkscape will have to be rebuild if you change/add something
 * in point.h ...)
 * An example of how to use this framework is lpe.test.cpp.
