For reasons I don't understand, the device pixel ratio was taken into account
twice. And as a result the transformation applied to the profile made us show
only the top left part of it - but enlarged (depending on the DPR).
This code fixes that problem by simply forcing the transformation used by the
painter to be the identity matrix. I worry that this could be wrong in some
situations, but for now it seems to fix the problem.

When in the planner, ESC should cancel the plan.
However, when the user manipulates the dive-handles in the
profile and presses ESC, first nothing happens, then an obscure
message appears.
The reason is that ESC "shortcuts" are introduced in two places.
To fix this, remove the ESC shortcut in the profile (the planner
widget cancels the plan anyway) and replace all the shortcuts in
the profile with a simple override of the keyPressEvent().
The latter is not strictly necessary, but hopefully avoids further
complications with multiple shortcuts. And the code is easier
to follow too.

The timestamp labels may change their format on zoom from
"mm" to "mm:ss", depending on the zoom level. Since the
animation kept old labels, this meant that one can end up
with a mix of labels.
Therefore, always reformat the labels. Of course, this
means that the labels switch instantaneously from one format
to the other. This is in conflict with the whole idea of
"smooth" animation. Such a smooth animation could be realized
by adding a "format" flag to the Label structure and keeping
thus fading in/out labels if the format changes. Do we want
that?

This prevented calculation of the pressure data when dragging
planner handles. However, this lead to weird artifacts.
As an alternative, if this turns out to be too slow, we might
disable the plotting of the pressure curves instead.
That said, even on my super-slow fanless laptop, this performs

In planner and edit mode, the cursor position is indicated using
crosshairs. They broke when changing to absolute scaling.
To fix them, remember the plot-area in the profile scene and
draw the crosshairs only inside this area (not on top of axes).
However, limit the position of the horizontal line to the
actual profile (dont paint inside the partial pressure, etc
graphs). The vertical line is painted above those graphs, so
that a timestamp can be related to partial pressure, tissue
loading, etc.
Also, set the z-value of the crosshairs. It was painted
inconsistently above some and below other chart features.

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"
to "show dive". However, that has bit-rotted away: the plotted
dive was set before plotting the dive and therefore the check
for "change from empty" did not work. Introduce an explicit

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.
Thus, we can avoid having the dive axes being QObjects.

This function was just needlessly complicated. For one, it

Positional bool parameters to control the rendering of the plot

Sadly, C++ has no reasonable way of defining flags that I know

ORed (enum class) or are weakly typed (int). Let's just use an

The old code used the maximum / minimum values of nine-minute
intervals to indicate maximum / minimum depths. This does not
work well when zooming, since the labels will get sparse.
Instead implement a primitive peak finding algorithm, that
searches for the deepest peak in the whole plot and then
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.
Only peaks of a certain prominence are considered, which
conveniently gives us the valleys.

Use variable intervals for printing temperature and heart
beat labels. Obviously, so that the labels don't become

There were two somewhat redundant flags for the axes: the position
(left, right, bottom) and the orientation (up-down, left-right, etc).
Replace the latter by an inverted flag: if true, the axis is
up-down or right-left, i.e. the opposite of what one would expect
for a normal graph.
Set the flag in the constructor and remove the setOrientation()
function.
Sadly, the code is a bit complex, because screen coordinates are
top-to-bottom. Who thought that would be a good idea?

axis.
