/**
* @brief The SvgppContext class provides a context containing SVG element
* callbacks for the SVG++ parser which is called from the SVG document
* traverser and forwards these callbacks to the SVG analyzer. It's separated
* from the SVG analyzer to avoid the very time consuming recompilation of the
* SVG document traverser when then SVG analyzer header is changed, which is
* expected to happen often as new functionality is added.
*
* Most of this is taken from
* http://svgpp.org/lesson01.html#handling-shapes-geometry.
