  24  * Class to create an svg file.
  25  * Provides method to add svg primitives like lines, rectangles, text.
  26  *
  27  * \remark this class is specifically tailored to the TSVN revision graph.
  28  * That's why the color params are Gdiplus::Color and not simple COLORREFs,
  29  * and also the styles and attributes of the used primitives are set
  30  * the way it's required for the revision graph.
