The placement of the axes was done independently of the
plotting, e.g. when settings changed. Presumably,
for performance reasons. However, since the axes may
depend on whether a dive has heart-rate data or not,
this simply is not viable. To make this work, one
would have to remember whether the previous dive
showed the heart-rate, etc. Not worth it - always
reposition the axes. It should not matte performance-
wise.

The DivePlotDataModel was saved with every event to access the

When creating the context menu on the profile, the code has

This was done by setting a special property on the item
and then checking for that property on the item that
the menu is invoked on or its parents.
The reason the code didn't simply check the pointer was
probably that DiveTextItem uses multiple inheritance:
It derives from QObject and QGraphicsItem. It has to derive
from QObject first, because (the ridiculously broken) MOC
needs it that way. The object added to the scene is a
QGraphicsItem. Thus, we get a pointer _into_ the DiveTextItem
object.
However, that's all completely unnecessary. We can simply
compare the pointers, as the compiler will understand that
QGraphicsItem is only the second base class of DiveTextItem.

initialized.
To avoid this sandwitching of profile- and model-initialization,
populate the dive handlers when switching the profile mode.
Thus, the profile can be switched into edit/plan mode when
the DivePointsPlannerModel is fully initialized.
This will be important in upcoming commits, when the initialization
of the dive is moved from the profile to the DivePointsPlannerModel.

The DivePlannerPointsModel::createTemporaryPlan() function had
two distinct and independent parts:
1) create the data points.
2) create the dive sample and calculate variations.
The second part was only exectuted if the recalc flag was set.
Out of the two callers, one was explicitly disabling and setting
the recalc flag to avoid the second part.
The much more logical thing is to simply split the function in
two and only call the first part.
To avoid any functional change, the second caller (the profile)
still tests for the recalc flag. However, if it shouldn't replot
a new plan, why calculate it in the first place!? And why does
the display function change the plan at all? This appears all
very ill-thought out and should be changed in due course.

When moving "dive handlers" with the cursor keys, the
profile was replot twice:
- First the recalculation of the planner model was suspended.
- The "stop" was moved.
- This led to a replot by a signal from the planner model.
However, the old profile was shown, since the recalculation
was suspended.
- The recalculation was reenabled.
- The profile war replot, resulting now in the correct profile.
A classical case of bit rot.
Instead, don't suspend calculation in the first place. This
shows the correct profile on the first replot and the second
replot can be removed.

The ItemPos structure describes the position of various chart
elements on the scene. It had two problems:
- The identifiers were starting with an underscore followed
by a capital letter. This is reserved to the compiler.
- The global object was initialized in the ProfileWidget's
constructor. This means that if there are multiple
ProfileWidgets, the structure is reinitialized even though
it is constant.
Remove the underscores (what was the point anyway?) and
initialize the structure in its own constructor. Moreover,
make the object const to drive the point home.
If this ever needs to be variable, each ProfileWidget
should get its own copy of the object.

So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()
functions.
This is necessary if we want to have multiple concurrent
profile objects. Think for example for printing or for mobile
where multiple dive objects are active at the same time.

Both loadFromDive() callers were clearing the model before
calling loadFromDive(). Move the clearing into that function
since it makes no sense to load into a non-cleared model.
Apparently this changes the way that no-cylinder dives are
treated and the code in ProfileWidget2::repositionDiveHandlers()
must now explicitly check for that condition.

There must not be two dive planner points at the same time
stamp, as this violates the laws of physics (and internal
assumptions).
The corresponding test was done in the profile code at
two different places with floating point arithmetics.
This is a bad idea, because
1) code duplication
2) danger of rounding issues
Instead, do this in one central point in the planner model
and use integer arithmetics. Simply add a few seconds until
a unique timestamp is obtained.

When moving the handle with the mouse, the old code tried
to be smart about changing the active handle when crossing
handles.
To me this always felt weird and it was inconsistent with

This model is only needed when in plan mode. To enable multiple
profilewidgets at the same time (e.g. for the mobile app or
for printing), make the pointer to DivePlannerPointsModel a
member variable that is initialized at construction time.
Moreover, allow passing null as the DivePlannerPointsModel,
in which case planning will be disabled. This will be useful
for simple printing.

When reordering the points, the DivePlannerPointsModel would
not emit the appropriate move signals, but simply a data-changed
signal over all elements. This obviously violates Qt's
model/view API, though it is probably harmless. Let's do
the right thing so that the frontend knows that the selected
item changed place.
Also, emit dataChanged only on the actually changed element,
not all elements.

The ProfileWidget2 slots, which reacted to model changes were
broken. They did not add / remove items at the changed positions,
but arbitrarily at the end. Moreover, they assumed that only
a single item was added / removed and thus violated the model/view
API.
This worked because the handles are completely reset after each
operation and the model only ever touched single items.
Nevertheless, this has to be fixed if we ever want finer grained
undo.

To remove reliance on global state, pass an "in_planner" argument

This is a bit sad, since the in_planner argument is now passed

There was code to create a fake dc in the profile widget in

The profile had a static variable which prevented animation
when first showing the profile. It appears more logical to
don't show the animation when switching from the empty state.

Remove this in a step to make the profile reentrant.
The code was quite ominous: instead of simply generating the

The profile item that shows the ceilings adds a warning event
if the ceiling is violated. This is very unfortunate.
Improve this situation by adding the event up to the function
that calculates the ceiling. This is still not how it should
be - the display layer should not modify the dive that it
displays.
To make this clear, add a comment that details that this
is a contract between planner and display layer: The planner
uses a dive that can be trampled upon by the profile.
Still, this should be solved differently.

The in_planner() function is incompatible with a reentrant
profile, since it accesses a global variable. In
create_plot_info_new() it is essentially redundant, because
there is a planner_ds (ds = deco_state) parameter that
is used only when in the planner. Therefore use that as
the in_planner indicator: when non-null, the profile is
showing a planned dive.

With the same argument as for DivePercentageItem, move access
to live data out of the paint() function. Instead, calculate
colors in replot(), where the other data are calculated.

The DivePercentageItem is a polygon-item with a custom paint()
method. Calculation of the polygon is done once in replot(),
but calculation of the corresponding colors is done in every
paint() call. The problem is, we have no control over paint().
It is called whenever Qt feels like. Therefore using live
dive data is a dangerous proposition if we ever want to get
rid of the global displayed_dive.
Do all the calculations in replot(). Store the colors in an
additional array of the same size as the polygon.

The only time the TankItem is replot is when new data is set.
Therefore, replot() can be folded into setData().

The code tried to only replot the profile if necessary, notably
when in edit mode or the ceilings are shown.
That seems like pointless premature optimization, which only
complicates things: The profile is replot every time a
"dive handle" is moved, which means that we depend on the
replotting being reasonably fast. Why should it then not
be redrawn if the settings change?
Let's remove this, as it makes control flow easier to reason
about.

The old mechanism to replot the profile items was to listen
to model-change signals. Then the code checked whether it
actually had to update anything by looking at the changed
model-indices.
However, the crucial replot was always initialized with
emitDataChanged(), which simple invalidated the full model
and therefore shouldCalculateStuff() always returned true.
Since now the replot() is called explicitly, remove the whole
logic and simply rename modelDataChanged() to replot().

On each profile replot, the gas axis was implicitly reset
by calling "dataModel->emitDataChanged()", which would send

and, more importantly, make order of execution deterministic,

Rename the function that resets the axis from "settingsChanged"

When the settings change, the depth axis is redrawn
to reflect metric/imperial units. To check whether the
units changed, the old length unit is saved in a static
