Berthold Stoeger 505e4e47eb profile: reimplement DivePercentageItem
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.

/* This is the Profile Item, it should be used for quite a lot of things
on the profile view. The usage should be pretty simple:
DiveProfileItem *profile = new DiveProfileItem(DiveDataModel, timeAxis, DiveDataModel::TIME, DiveDataModel, DiveDataModel::DEPTH, dpr);
scene()->addItem(profile);
This is a generically item and should be used as a base for others, I think...
