9bca38afcf profile: recalculate profile info when switching from empty state
When the profile was to small, it would switch into empty state
and clear the plot info.

On resize events, the plot info is not recalculated.

This means that when making the profile extremely small and
then bigger, nothing is shown.

This may also happen on startup. The profile is rendered into
a 0x0 widget and then gets a resize event.

Therefore, remember when the profile is empty and force a
recalculation of the plot info.

94641c510f core: create range.h header for range manupulation functions
The moveInVector() function was defined in qthelper.h, even
though it has nothing to do with Qt. Therefore, move it into
its own header.

Morover, since it is a very low-level function, use snake_case.
And rename it to move_in_range(), because it does not only
work on vectors, but any range with random-access iterators.

24926f6031 profile: don't use displayed_dive to check whether dive changed
The profile replots if the mode of the currently displayed
dive changed. To do so, it compares the changed dive to
the displayed_dive. However, that is only used for planned
dives since quite some time.

edf2a2f4f4 profile: implement panning of profile
When zoomed in, the profile position was moved by hovering with
the mouse. What a horrible user experience. This is especially
useless if we want to implement an interactive profile on mobile.

Instead, let the user start the panning with a mouse click. The
code is somewhat nasty, because the position is given as a
real in the [0,1] range, which represents all possible positions
from completely to the left to completely to the right.

This commit also removes the restriction that the planner handles
can only be moved when fully zoomed out. It is not completely
clear what the implications are. Let's see.

ada4632ff1 profile: remove last dc_number access from profile code
dc_number is a global variable indicating the currently displayed
dive on desktop. It makes no sense on mobile, since multiple
profiles can be active at the same time. Therefore, the profile
code should not access this global, but use the dc number that
is passed in.

This removes the last access.

ed83f6ce32 profile: only keep pointer to plot_info in ruler objects
Now this one was strange:

The ruler items keep a copy of the plot_info struct. However,
only a shallow copy is made (the actual plot data is not copied).
This means that the data is only valid as long as the source
plot_info is valid. But if that is guaranteed, we simply can
keep a pointer instead of the full object.

I wonder if it wouldn't be better still to keep a pointer to
the profile and query that for the plot info?

c2a7382b10 mobile: better scaling of profile items
With all the recent changes, some of the previous assumptions about the scale
of items seem to be no longer appropriate. Now that we are showing the icons in
the profile again on device it's quite obvious that they were way too big -
clearly we don't need the special scaling anymore.

Also implement a suggestion from Berthold to get slightly smaller fonts and
finer structures in the profile on mobile devices. This scaling of the DPR
seems to work well in my tests.

only on "saving". Move the edit-mode from the mainwindow
and the maintab to the profile widget.

This is still very rough. For example, the only way to exit

59fe2f3d7e cleanup: prevent distracing conversion warnings
We do want the -Wfloat-conversion warnings where they point out
potential bugs. But they are very distracting when they are triggered by
floating point literals (which the standard defines as double) passed to
a function expecting float arguments.

The fact that Qt6 changes the arguments to all these functions from
double to float is... hard to explain, but it is what it is. With these
changes, for the majority of cases we create inlined helpers that
conditionally compile to do the right thing. And in a handful of other
cases we simply cast to float (and accept that on Qt5 this then gets
cast back to double... for none of these cases the potential loss in
precision makes any difference, anyway - which likely is why the Qt
community made the decision to change the type of the arguments in the
first place).

f8eb5140e2 mobile/profile: fix scaling of profile for HDPI screens
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.

777a57356b profile: fix ESC in planner
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.

3ae160857d profile: reformat timestamp labels
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?

352cdcc863 profile: fix crosshairs
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.

6f2965c5af profile: access profile data directly
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.

Positional bool parameters to control the rendering of the plot
have been a pain. We are down to one parameter (instant),

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

7ef0ae02a8 profile: implement adaptive depth markings
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.

modern desktop anyway. It might make sense on mobile, where
size changes are discontinuous, but there we use static
profiles anyway. Moreover, I checked a few applications and

177df72d33 profile: unify formating of axis labels
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
via a flag.

This is all done not so much for code simplification, but
because for a general layout of the axis labels, the
axis has to understand the values of the labels and not
only handle them as opaque texts.

This is not so much an optimization thing, but rather an

will always be an exception. But hopefully the remaining

the labels for the temperature axes are not converted to
F if needed. And therefore also not shown. This will need
