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
mouse-move. Theregore, simply do nothing special at all. The
user should hopefully get an intiutive grasp of what's going
on when moving one handler across another.

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
to AbstractProfilePolygonItem::replot(). Thus, calls to in_planner()

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

from AbstractProfilePolygonItem. However, it is only needed
for one, viz. DiveGasPressureItem. Well, perhaps in the future
more features will depend on the planner mode...

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.
This removes global state, as a function static variable

The DiveHandler shows a context menu where a cylinder can be
chosen. This indirectly accesses the global displayed_dive
variable.
Remove this in a step to make the profile reentrant.
The code was quite ominous: instead of simply generating the

with Qt's cumbersome model/view API. All this trampling over

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.
This is slightly more complicated than in DivePercentageItem,

by a vector of structures contained the position and color
of the data point.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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 good thing is that setData() is passed the dive to be

the global displayed_dive variable.

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.
This makes the isPlotZoomed member variable redundant. Remove it.

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().

Instead of listening to the dive-data-model changed and
axis changed signals, update the profile items explicitly
once per plot() call. This avoids double replotting of the

dataModel->emitDataChanged().

On each profile replot, the gas axis was implicitly reset
by calling "dataModel->emitDataChanged()", which would send
a signal recieved by the axis. To make the code less confusing
and, more importantly, make order of execution deterministic,
explicitly reset the axis.
Rename the function that resets the axis from "settingsChanged"
to "update" to reflect its usage.
Moreover, remove the "setModel()" function and pass the model
to the constructore. Make it a const reference to make clear
that it can't change during the life time of the axis.

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

This one is extremely obscure: TankItem::setData(), which is
called on every replot, was passed the DivePlotDataModel,
even though it doesn't access that model at all.
Instead, it connect()s to the model to stay informed of changes
to the data. First of all, this should obviously be done
once in the constructor, not on every replot.
But also, the setData() function is called on every replot
one lines before sending the model-changed signal.
Thus, the tankitem was always repainted twice.
Just remove the whole connect() thing and go for a more
deterministic model. Should the tankbar not be repainted
anywhere, add the appropriate calls there.
Accordingly rename the "modelDataChanged" slot to "replot".

settingsChanged() is a virtual function, which is called
when the preferences dialog signals changes. In most derived
classes, the function does nothing.
In two classes, DiveProfileItem and DiveCalculatedTissue, it

dialog. Indeed, the functions are also connected to finer-grained
