For better scalability, we might replace the dive event icons
by SVGs. Since rendering SVGs is potentially very slow, cache
the pixmaps when the scene is generated.
Note: this does not yet do any SVG rendering, only the caching
of pixmaps.

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.

Since there (currently) is no interactive widget on mobile, there
is no point in compiling it. This was a bit more complicated than
expected, since there were other source files (divehandler.cpp
and ruleritem.cpp) which reference ProfileWidget2 and therefore
need to be removed. Otherwise, the dreadful MOC produces unresolved
references.
We could now remove all the conditional compiles in
profilewidget2.cpp, but let's keep them for now. We might have
to readd a number of them later, when making the mobile-profile
interactive.

This simply subclasses QGraphicsScene and is used as
a drop-in replacement. The plan is to step-by-step
move rendering functions there until the non-interactive
code can only use the scene and doesn't have to use
the QGraphicsView. This will hopefully remove quite
some conditional code.

These are the small dots that describe dragable points on
the profile when in the planner. It makes no sense to have
them in desktop's planner-widget code. They belong to the
profile.
Therefore, move the code there and compile on mobile.
Not everything can be compiled on mobile for now, but it
is a start.

qmlprofile.* is part of profile-widget, and are now defined in the
the corresponding CMakeLists.txt, and thereby making the central
CMakeLists.txt cleaner.

The reason for that is, even if profile widget is made with qpainter
and for that reason it should be a desktop widget, it's being used
on the mobile version because of a lack of QML plotting library that
is fast and reliable.
We discovered that it was faster just to encapsulate our Profile in
a QML class and call it directly.
