/**
* \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.
