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. + *//* + * Copyright 2009 Johan Engelen <goejendaagh@zonnet.nl> + * + * This library is free software; you can redistribute it and/or + * modify it either under the terms of the GNU Lesser General Public + * License version 2.1 as published by the Free Software Foundation + * (the "LGPL") or, at your option, under the terms of the Mozilla + * Public License Version 1.1 (the "MPL").
