/** \brief functor used to draw a custom JKQTPGraphSymbols
* \ingroup jkqtptools_drawing
*
* Draw the symbol with these properties:
* - center at (0,0)
* - width 1, i.e. x=-0.5...0.5
* - height 1, i.e. y=-0.5...0.5
* - you can assume that a proper pen and brush is set with the correct properties
* - scaling to the final size is donw by JKQTPPlotSymbol()
* - drawing is protected by surronding \c p.save(); and \c p.restore(); in JKQTPPlotSymbol()
* .
*
* As an example, the following code-snippet:
* \code
* [](QPainter& p) {
* p.drawEllipse(QPointF(-0.2, -0.2), 0.3, 0.3);
* p.setBrush(Qt::NoBrush);
* p.drawEllipse(QPointF(0.2, -0.2), 0.3, 0.3);
* p.drawEllipse(QPointF(0, 0.2), 0.3, 0.3);
* };
* \endcode
* generates this symbol: \image html symbols/symbol_custom.png
