Default impl: just call paint.
Derived classes like KDChart::AbstractArea are providing additional action here.
Reimplemented in KDChart::AbstractArea, KDChart::TextArea, and KDChart::TernaryAxis.

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.
Thus, you need to call setParentWidget on every item, that has a non-fixed size.
