/**
* Class containing the basic options for renderers.
*
* Renderer options are used to define the general appearance of charts beside
* the palettes. The renderer transforms chart primitives (like the legend, or
* one pie slice) into image primitives, which are then rendered by the
* drivers. The way this transformation is done, and which effects are also
* rendered is specified by the values in this option class.
*
* The example below shows some basic bar rendering options, which are
* available in all renderers. You mya want to check the tutorial sections
* about the renderer, which show example output for more renderer options.
*
* <code>
* $wikidata = include 'tutorial_wikipedia_data.php';
*
* $graph = new ezcGraphBarChart();
* $graph->title = 'Wikipedia articles';
*
* // Add data
* foreach ( $wikidata as $language => $data )
* {
* $graph->data[$language] = new ezcGraphArrayDataSet( $data );
* }
*
* // $graph->renderer = new ezcGraphRenderer2d();
*
* $graph->renderer->options->barMargin = .2;
* $graph->renderer->options->barPadding = .2;
*
* $graph->renderer->options->dataBorder = 0;
*
* $graph->render( 400, 150, 'tutorial_bar_chart_options.svg' );
* </code>
*
* For additional options, which are special to some chart type you may
* also want to check the option classes for the repective chart type you
* are using and the elements of the chart. The chart type dependant option
* classes are:
*
* - ezcGraphLineChartOptions
* - ezcGraphPieChartOptions
* - ezcGraphRadarChartOptions
*
* There may be additional options dependant on the renderer you are using.
* You may want to check the extensions of this class:
*
* - ezcGraphRenderer2dOptions
* - ezcGraphRenderer3dOptions
*
* @property float $maxLabelHeight
* Percent of chart height used as maximum height for pie chart
* labels.
* @property bool $showSymbol
* Indicates wheather to show the line between pie elements and
* labels.
* @property float $symbolSize
* Size of symbols used to connect a label with a pie.
* @property float $moveOut
* Percent to move pie chart elements out of the middle on highlight.
* @property int $titlePosition
* Position of title in a box.
* @property int $titleAlignement
* Alignement of box titles.
* @property float $dataBorder
* Factor to darken border of data elements, like lines, bars and
* pie segments.
* @property float $barMargin
* Procentual distance between bar blocks.
* @property float $barPadding
* Procentual distance between bars.
* @property float $pieChartOffset
* Offset for starting with first pie chart segment in degrees.
* @property float $legendSymbolGleam
* Opacity of gleam in legend symbols
* @property float $legendSymbolGleamSize
* Size of gleam in legend symbols
* @property float $legendSymbolGleamColor
* Color of gleam in legend symbols
* @property float $pieVerticalSize
* Percent of vertical space used for maximum pie chart size.
* @property float $pieHorizontalSize
* Percent of horizontal space used for maximum pie chart size.
* @property float $pieChartSymbolColor
* Color of pie chart symbols
* @property float $pieChartGleam
* Enhance pie chart with gleam on top.
* @property float $pieChartGleamColor
* Color used for gleam on pie charts.
* @property float $pieChartGleamBorder
* Do not draw gleam on an outer border of this size.
* @property bool $syncAxisFonts
* Synchronize fonts of axis. With the defaut true value, the only
* the fonts of the yAxis will be used.
* @property bool $axisEndStyle
* Style of axis end markers. Defauls to arrow heads, but you may
* also use all symbol constants defined ein the ezcGraph class,
* especially ezcGraph::NO_SYMBOL.
* @property bool $shortAxis
* Defines wheather to render the axis extending the chart boundings
* or stop them at the chart boundings. Deafults to false.
