/**
* GOTCHA:
*   This file is used mainly for drawing UML diagram in PNG or SVG format,
*   currently pixel by pixel,  when HAVE_DOT = NO.
*   This file is not used at all if HAVE_DOT = YES.
*
*   To increase SVG support another add-on must be included
*   into the generating DOT UML format source code.
*
*   More SVG optimization should be provided,
*   most drawing are simple polygon,
*   text could be predefined in a <defs> and called with <use id='#f'/>
*   or used as <text> with normal fonts or create a custom SVG font.
*   Only letters which are used are required.
*
* NOTICE:
*   <defs> and <font definition> can be written anywhere in any order
*   inside the <svg>..</svg> tags.
