In analogy to the other charts, highlight selected pie slices. Overlay them with a checkerboard pattern, like in the bar charts. Since all charts now support highlighting, the divesSelected() virtual function now doesn't need a default implementation anymore. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
