The tissue percentages were realized as 16 independent polygons. That didn't work at all with the new absolute scaling. Reimplement the item and blast it onto a pixmap. Not only is this artifact-free, it also should (hopefully) be quite a bit more efficient than painting numerous lines. In contrast to the old code, this does access the plot_info structure directly instead of using the model. Not so much for performance reason, but rather to make things more robust: We have a strongly typed language. Why would we shoehorn data through the weakly typed QVariant and mess with wierd index-arithmetics. Makes no sense to me. Qt-model have to be used for interfacing with Qt. They are terrible for intra-application data transfer. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
