  *  \section      secGraphicsStructure  General Structure of the Graphics Object
  *
  *                First, the Graphics object is a singleton that has to be
  *                accessed through the static getGraphics methods.
  *
  *                The Graphics object contains a set of DisplayStyles of which
  *                one is active at a time and so used to do all drawings.
  *                Each DisplayStyle is identified though a name and can be
  *                selected with the setStyle() method.
  *
  *                The DisplayStyle itself is a set of DrawingStyle.
  *                Each DrawingStyle is named and provides a QColor, a QPen
  *                and a QBrush. QColor, QPen & QBrush are build from the
  *                \c (red,green,blue) , \c BorderWidth and \c pattern .
  *
  *                Direct access to the DrawingStyle: once a DisplayStyle has
  *                been selected, the Graphics accessors getColor(), getPen()
  *                or getBrush() gives you access to the DrawingStyles.
  *
  *                Minimal DisplayStyle: any DisplayStyle contains at least
  *                the following DrawingStyles :
  *                <ul>
  *                  <li>\b Fallback : the default DrawingStyle.
  *                  <li>\b Background
  *                  <li>\b Foreground
  *                  <li>\b Rubber
  *                  <li>\b Phantom
  *                  <li>\b Boundaries
  *                  <li>\b Marker
  *                  <li>\b SelectionDraw
  *                  <li>\b SelectionFill
  *                  <li>\b Grid
  *                  <li>\b Spot
  *                  <li>\b Ghost
  *                  <li>\b Text
  *                  <li>\b Undef
  *                </ul>
  *
  *                Configuration parsers should create a DrawingStyle for each
  *                BasicLayer, with the name of the BasicLayer as the key. So the
  *                following code should be valid :
\code
  QBrush layerBrush = Graphics::getBrush ( layer->getName() );
\endcode
  *                If no DrawingStyle of that name is defined, the \b Fallback
  *                will be used.
