The profile was using a Qt-model to access its data. This means
routing everything through Qt's QVariants and lead to verbose
code such as
double prev_y = dataModel.index(i-1, vDataColumn).data().toReal();
Instead of storing a data-column and do access via a template,
simply store accessor functions. The code from above now reads as
double prev_y = accessor(data[i-1]);
This should also be distinctly faster for the ns-optimizers among
us.
Only one case was somewhat nasty to convert: The accessors for
the 16 tissues are now generated via a recursive template. Thanks
to C++17's constexpr if, such a template is pleasantly easy
to follow, though.

There was logic to disable animation when switching from "no dive"

The old animation was weird: it would reuse the labels
based on the index, not on the value. Thus, with the
new scaling code, sometimes there was no animation at all,
if the value, but not the position changed.
Consider the values instead and let labels appear/disappear.
This makes things slightly more complex.
While changing this code, create our own animation-class.

The old code used the maximum / minimum values of nine-minute

repeats the procedure for the right and left sides, leaving
out a certain distance to the origninal peak. This is repeated
until there are no more peaks found.

Instead of a host of virtual functions, let the base class
(DiveCartesianAxis) do the formatting of the axis labels.
To do so, it needs to know how to convert the internal
representation (e.g. mm) into the displayed value (e.g. feet).
Moreover, this transformation has to be adapted when changing
the locale-setting, therefore do it for every plot() call.
The transformation itself cannot be a simple linear translation,
because we have non-absolute display units, namely °C and °F.
Thankfully affine transformations are enough though.
Only one custom formatter remains: the time axis. It might
be a good idea to remove the virtual function and do this

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.

The usage of the DiveProfileItems has changed (axes, etc. are passed
at construction time). Update a comment accordingly.

The font print scale is now set once on construction and this
function can therefore be removed.

Instead of intializing the text fields and then changing the
font scale via signal-rigmarole, pass down the font-scale
at construction time.
Since the fontPrintScale is only set in print mode, we also
can access it directly instead of testing for printMode.
Since the DiveTextItem is not updated using signals anymore,
the connected flag can be removed.
The commit is larger than I had hoped for, but this makes
things ultimately less brittle.

The constructors of Time- and TemperatureAxis don't do anything.
In reasonable modern C++ we can simply reuse the constructor
of the base class with a "using" directive.
The point here is to simplify followup commits that will
add additional parameters to the constructors of the axes.

This was only used internally - there is no point in an
accessor function. It only makes grepping more complicated.

Not having to readjust the scale on-demand will make the
code distinctly simpler. Let's just pass it once.
