PrerenderedLabel is an internal KDChart class that simplifies creation and caching of cached text labels.
It provides referenze points to anchor the text to other elements. Reference points use the positions defined in KDChartEnums.
Usage:
double angle = 90.0;
CachedLabel label;
label.paint( font, tr("Label"), angle );
