The goal here is to add general addition and scalar multiplication
functions to the unit types.
Thereto, we need a CRTP
(https://en.wikipedia.org/wiki/Curiously_recurring_template_pattern)
base class.
However, this breaks compound initialization, so we have to use
named initializers:
weight_t { 2000 } -> weight_t { .grams = 2000 }
The good thing is that this is exactly how these classes were
supposed to be used: make the unit explicit!

Since struct divecomputer is now fully C++ (i.e. cleans up
after itself), we can simply turn the list of divecomputers
into an std::vector<>. This makes the code quite a bit simpler,
because the first divecomputer was actually a subobject.
Yes, this makes the common case of a single divecomputer a
little bit less efficient, but it really shouldn't matter.
If it does, we can still write a special std::vector<>-
like container that keeps the first element inline.
This change makes pointers-to-divecomputers not stable.
So always access the divecomputer via its index. As
far as I can tell, most of the code already does this.

This is a rather long commit, because it refactors lots of the event
code from pointer to value semantics: pointers to entries in an
std::vector<> are not stable, so better use indexes.
To step through the event-list at diven time stamps, add *_loop classes,
which encapsulate state that had to be manually handled before by
the caller. I'm not happy about the interface, but it tries to
mirror the one we had before.

This is a hairy one, because the sample code is rather tricky.
There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.
Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().
Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

Use more C++ style memory management for plot_info: Use std::vector
for array data. Return the plot_info instead of filling an output
parameter. Add a constructor/destructor pair so that the caller
isn't bothered with memory management.
The bulk of the commit is replacement of pointers with references,
which is kind of gratuitous. But I started and then went on...

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.

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.

dc_number is a global variable indicating the currently displayed

profiles can be active at the same time. Therefore, the profile
code should not access this global, but use the dc number that

This prevented calculation of the pressure data when dragging

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.

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 used to check wether a screen-point

We were using the QGraphicsScene machinery to zoom into the
plot. This not only zoomed into the dive, but into the whole
thing. In general, one couldn't see the axes anymore.
Instead, adjust the range of the time-axis according to the
zoom-level and position.
Of course, the code isn't adapted to that and the result
is comical. The chart features will have to be fixed
one-by-one. Oh joy.

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?
Note: this also fixes the placement of the ticks of the time
axis.

The visibility of axis text / lines is never changed, so set
in axis constructor.
Moreover, instead of rendering the lines/text and then setting
them invisible, do not render them if invisible.
The whole thing appears superfluous, since the proper way to
not show lines/text is to just not call updateTicks on the
axis. But in the future we might want to have axes with text
but no lines, so keep for now.
Since this means breaking out the text / line rendering
into their own function, we might rename some variables to
make them (at least somewhat) more clear.

The ticks were recalculated twice per plotDive() call:
1) When updating the position of the axes in updateChangeLine()
2) After setting the bounds in plotDive() via setBounds()

is always redundant. Moreover, rename the function to setPosition(),

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.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Instead of calculating the label sizes of the axes when
relayouting the chart, calculate them at construction time.
To do so, pass the digits before and after the decimal comma
to the constructor.
This is not so much an optimization thing, but rather an
first stab at more general label rendering. Time, of course,
will always be an exception. But hopefully the remaining
values can be done more generally.
Note that currently this code is a total mess. For example,
the labels for the temperature axes are not converted to
F if needed. And therefore also not shown. This will need
some major rethinking.
