The current way of handling the "print scale factor" is
complex: The text fields are added and later resized via
signals. Things could be simplified by just redoing the
chart when changing the scale factor.
Moreover, in the future we will want to adapt the size of the
axes depending on the size of the texts.
As a first step, factor out the creation of the profile-widget.
This can then be used to recreate the profile when changing
the scale factor.

Very annoyingly, to render the profile for printing / export,
the profile still had to be show()n, thus requiring a parent
window.
Analysis of qmlprofile.c showed that this was due to the
transformation matrix not being properly set up on non-show()n
scenes.
Instead, we can simply render via the QGraphicsScene
(circumventing the QGraphicsView).
The code was factored out into the ProfileWidget2::draw()
function. This will hopefully make it easier to change

When creating the context menu on the profile, the code has
to check whether the context menu is activated on the
dive computer name to show a special menu (delete / split
dive computer).
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.

When switching to the "plan" or "add" (which should rather be
called "edit", by the way) mode of the profile, the "shortcuts"
for copy&paste, undo&redo, etc. are disabled. When switching
to "profile" mode, they are reenabled.
This was done in a most convoluted way:
- The MainWindow calls the set*State() function of the profile.
- The Profile emits [disable|enable]Shortcuts() signals.
- The MainWindow catches these signals and does the enabling
or disabling.
Not only is this very hard to reason about, it is also in
contradiction to the profile being part of the display layer.
Moreover, in editCurrentDive() the MainWindow disabled the
shortcuts itself, so this was all redundant.

In planner or profile-edit mode, the plotDive() function takes
the current plan and turns it into a dive profile. Not only
is this a layering violation (the display layer modifying the
dive), it is also fundamentally flawed. The control-flow is
out of control, if you wish. There are numerous reasons why
the profile needs to be replot, many of which do not need
a recalculated dive profile.
Move the code that updates the dive-profile to the
DivePlannerPointsModel. Thus, the profile recalculations
and replots can be pooled. This will break the planner, since
there now might be missing calls to the profile recalculation.
But it already has some positive effects: when removing
multiple points, the profile is only recalculated once.

The dive handlers are only updated by signals. This means that

1) initialize the DivePointsPlannerModel
2) switch profile mode
3) load dive into DivePointsPlannerModel
2) and 3) cannot be exchanged, or the dive handlers are not

To avoid this sandwitching of profile- and model-initialization,
populate the dive handlers when switching the profile mode.

the DivePointsPlannerModel is fully initialized.

The DivePlannerPointsModel::createTemporaryPlan() function had

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

Instead of listening to the dive-data-model changed and

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

initialized in the constructor.

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".

The DiveCalculatedCeiling profile-item has a recalc()
function, which calls "dataModel->calculateDecompression()".
This is a questionable reversal of control-flow: The
profile-item should paint the model-data not change it.
The code was supposed to be called under two conditions:
1) The value of the calcceiling3m preferences flag changed.
This code was buggy for two reasons: Firstly, the cached
value was always initialized to false, which means that
sometimes the first call was missed. Secondly, the
settingsChanged() functions was only called when closing
the preferences window, not when changing the flag in the
profile widgets.
2) The datetime of the dive changed. The whole control-flow is
pretty absurd (due to "bit rot"):
- The replan-dive command sends a date-time changed signal.
- The main tab changes the date-time and informs the profile.
- The profile sends a signal to the item.
- The item instructs the model to recalculate the
decompression.
- The model causes the profile to be redrawn.
In any case, the whole thing is moot, because the decompression
is recalculated for *every* profile plot in create_plot_info_new().
Let's remove the code from the DiveCalculatedCeiling profile-item
and the calculateDecompression() function, which is now not
used anymore.

On clicking the DivePictureItem "trash" icon, the item would delete
the picture it represents in the currently displayed dive. This needed
an access to the global "displayed_dive" variable, which we want

One solution would be to save the dive with every DivePictureItem.

ProfileWidget2::plotDive() had this weird interface, where passing
in NULL as dive would mean "show current_dive". However, most callers

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit

The ProfileWidget2::recalcCeiling() function is used in one place,
namely when an undo-command changes the mode. It recalculates
decompression data and repaints the ceilings and thus avoids a
full profile-redraw.
This is smart, but it becomes problematic when the dive is changed
and the ceiling is recalculated before the profile is redrawn.
The DivePlotDataModel then still has data from the previous dive
but cylinders of the new dive are accessed.
This kind of situation may arise if multiple dive fields are
updated, as for example when replanning a dive.
Currently, this only causes a temporary mis-calculation. When
removing MAX_CYLINDERS this will lead to crashes.
One might attempt to fix the whole data-dependency mess. This

the mode is changed. Yes, it is in a way ineffective, but we
do worse things. The ProfileWidget2::recalcCeiling() thus becomes
unused and is removed.

TankItem had a "height" member variable that was never modified.
Turn it into a constant, which is local to the translation unit.

The whole plot info data was copied only so that the time of the
last item could be determined later. Instead, simply store the
timestamp.

Calculation of the x-position and the width of the tank-bar
was done outside of the function. Move it into the function
to make the caller a bit more readable.

This is only used for an "is initialized"-check. But there are
other member variables that are used for that purpose. Remove.

I'm a bit confused why this enum has two extra values, NUM_DIVEMODE and
UNDEF_COMP_TYPE. I can see how this could create confusion. This may
benefit from addition review.

Since requiring Qt >= 5.9.1, we can use the pointer-to-member-function
overloads of addAction (introduced in Qt 5.6). This has the advantage
of compile-time checking of the signal/slot parameters.
