Chart element to display texts in a chart

Chart elements can be understood as widgets or layout container inside the
chart. The actual transformation to images happens inside the renderers.
They represent all elements inside the chart and contain mostly general
formatting options, while the renderer itself might define additional
formatting options for some chart elments. You can find more about the
general formatting options for chart elements in the base class
ezcGraphChartElement.

The text element can only be placed at the top or the bottom of the chart.
Beside the common options it has only one additional option defining the
maximum height used for the text box. The actaully required height is
calculated based on the assigned text size.

<code>
$chart = new ezcGraphPieChart();
$chart->data['example'] = new ezcGraphArrayDataSet( array(
'Foo' => 23,
'Bar' => 42,
) );

$chart->title = 'Some pie chart';

// Use at maximum 5% of the chart height for the title.
$chart->title->maxHeight = .05;

$graph->render( 400, 250, 'title.svg' );
