/**
* Class containing the basic driver options.
*
* Most of the options of the driver class, like the width, height and font are
* set internally by the driver and not really relevant to the user of driver
* classes. You can configure how strings are automatically shortened, together
* with the postfix, which is appended to shortened strings, like the following
* example shows.
*
* Configuration options, which special to the actual drivers are configured in
* the driver specific extensions of this option class.
*
* <code>
* require_once 'tutorial_autoload.php';
*
* $graph = new ezcGraphPieChart();
* $graph->palette = new ezcGraphPaletteEzBlue();
* $graph->title = 'Access statistics';
*
* $graph->data['Access statistics'] = new ezcGraphArrayDataSet( array(
* 'Mozilla' => 19113,
* 'Explorer' => 10917,
* 'Opera' => 1464,
* 'Safari' => 652,
* 'Konqueror' => 474,
* ) );
*
* // Do not shorten strings automatically if they do not fit in the assigned
* // space with the minimum font size.
* $graph->driver->options->autoShortenString = false;
*
* $graph->render( 400, 150, 'tutorial_chart_title.svg' );
* </code>
*
* @property int $width
* Width of the chart.
* @property int $height
* Height of the chart.
* @property float $shadeCircularArc
* Percent to darken circular arcs at the sides
* @property float $lineSpacing
* Percent of font size used for line spacing
* @property int $font
* Font used in the graph.
* @property bool $autoShortenString
* Automatically shorten string if it do not fit into the available
* space, even with the minimum font size used. Deactivating this
* setting will result in ezcGraphFontRenderingException exceptions,
* informing you about the actual string which did not fit.
* @property string $autoShortenStringPostFix
* String to append to shortened strings, if there is enough space
* left for the postfix.
