/**
* Struct to represent the context of a renderer operation
*
* Objects of this class are passed to the renderer, so the renderer is able to
* maintain the associations between image primitives and the datpoints. With
* this information the renderer build the array returned by the
* getElementReferences() method of the ezcGraphRenderer classes. In the
* returned array the datapoints are then associated with the identifiers for
* the image primitives returned by the respective driver.
*
* The ezcGraphTools class offers convience methods to handle this data and
* enrich your charts with hyperlinks, so you don't need to handle this
* yourself.
*
* The struct contains information about the $dataset and $datapoint the
* image primitive is associated with. If the dataset or datapoint has an
* URL associated, this URL is also available in the context struct.
