The printFontScale is used to scale up fonts (and icons) when
rendering to high-DPI devices. With absolute scaling, this
will also be used to scale the size of different chart
regions, line thickness, etc. Therefore, give it an more
appropriate name. "Device pixel ratio", which is a well
established term, seems to appropriately describe the
concept.

Instead of using the interactive ProfileWidget2, just
use the ProfileScene to render the profile for printing,
export and mobile. One layer (QWidget) less.
This removes all the kludges for handling DPR on mobile.
Thus, the rendering will now be off and have to be fixed
by redoing the scaling code.

Setting the profile and grayscale mode of the profile via
functions is from a time when the same profile widget was
used for printing and the UI. It is simpler to set the mode
when constructing the object and not deal with changes.
To prepare for this scenario, take the flag at construction
time. This still keeps the callers as-is. These will be
adapted later.
Logically, then the printFlag also has to be set in
DiveCartesianAxis at construction time.

The cartesian axes use animSpeed to animate changes. Instead
of passing down the value to the respective functions, the
speed was stored in the ProfileScene and the axes would
access it there. Very messy. Let's just pass down the speed.
There still are back-references from the axes to the scene,
notably to place labels "outside" of the scene. Let's try
to remove them later.

This finalizes the split between interactive (ProfileWidget2)
and non-interactive (ProfileScene) parts of the profile.

Since the ProfileScene does the actual rendering, it needs
access to the "printMode", "isGrayScale" and "fontPrintScale"
variables. Move them down from ProfileView to ProfileScene.

Part of separating the static (for printing, export) and
dynamic (UI) parts of the profile. This is still quite messy
with many direct accesses from the ProfileWidget.

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.
