To layout the profile we need to determine the height
of texts. Add versions for a DiveTextItem and a static
function, which is passed the scale and dpr. The latter
is used to setup items, where we do not necessarily
have a text at creation time (e.g. the tankbar).

To properly layout the profile we need to know the expected space
required by the vertical axes. In the general case, format the
the text "999". For the partial-pressure-axis, use "0.99".

The printFontScale is used to scale up fonts (and icons) when
rendering to high-DPI devices. With absolute scaling, this
will also be used to scale the size of different chart
regions, line thickness, etc. Therefore, give it an more
appropriate name. "Device pixel ratio", which is a well
established term, seems to appropriately describe the
concept.

Since there (currently) is no interactive widget on mobile, there
is no point in compiling it. This was a bit more complicated than
expected, since there were other source files (divehandler.cpp
and ruleritem.cpp) which reference ProfileWidget2 and therefore
need to be removed. Otherwise, the dreadful MOC produces unresolved
references.
We could now remove all the conditional compiles in
profilewidget2.cpp, but let's keep them for now. We might have
to readd a number of them later, when making the mobile-profile
interactive.

Instead of using the interactive ProfileWidget2, just
use the ProfileScene to render the profile for printing,
export and mobile. One layer (QWidget) less.
This removes all the kludges for handling DPR on mobile.
Thus, the rendering will now be off and have to be fixed
by redoing the scaling code.

Setting the profile and grayscale mode of the profile via
functions is from a time when the same profile widget was
used for printing and the UI. It is simpler to set the mode
when constructing the object and not deal with changes.
To prepare for this scenario, take the flag at construction
time. This still keeps the callers as-is. These will be
adapted later.
Logically, then the printFlag also has to be set in
DiveCartesianAxis at construction time.

The cartesian axes use animSpeed to animate changes. Instead
of passing down the value to the respective functions, the
speed was stored in the ProfileScene and the axes would
access it there. Very messy. Let's just pass down the speed.
There still are back-references from the axes to the scene,
notably to place labels "outside" of the scene. Let's try
to remove them later.

The mode of the profile (profile, edit, plan) was set in
MainWindow and ProfileWidget. For consistency move the one
setProfileState() call from MainWindow to ProfileWidget.
This removes a direct access to the profile-view and
therefore improves encapsulation.
Also, clear the profile, when no dive is shown to remove
any potentially dangling references.

This was moved to the desktop version. Enter the profile in
the constructor. Somewhat surprisingly, this seems to work.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The profile has an "empty state" showing the subsurface logo,
which is active when no dive is selected.
Switching to/from this mode is quite complex, because all the
chart features have to be hidden/shown, etc. Moreover, this mode
is not needed on mobile, where multiple ProfileWidgets can
be active at the same time and every dive has at least a
"faked" profile.
Therefore, implement this mode directly in the desktop
version of the widget. This makes the rescaling distinctly
less cumbersome. It is implemented using a QStackedWidget,
which switches between the profile and the logo.
This commit does not remove the empty state from the profile.

This simply subclasses QGraphicsScene and is used as

code can only use the scene and doesn't have to use

some conditional code.

The font print scale is now set once on construction and this

Instead of intializing the text fields and then changing the
font scale via signal-rigmarole, pass down the font-scale
at construction time.
Since the fontPrintScale is only set in print mode, we also
can access it directly instead of testing for printMode.
Since the DiveTextItem is not updated using signals anymore,
the connected flag can be removed.

things ultimately less brittle.

The constructors of Time- and TemperatureAxis don't do anything.
In reasonable modern C++ we can simply reuse the constructor
of the base class with a "using" directive.
The point here is to simplify followup commits that will
add additional parameters to the constructors of the axes.

Thus, we can keep the scale factor constant during existence
of the view. For now, this is simpler than adapting existing
text elements. We might want to make this more flexible later.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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
the size-code of the profile.

Create a new class that encapsulates the profile-widget UI.
This is called ProfileWidget, which might be confusing since

Just as for printing, use an independent profile widget, so
that the UI widget doesn't have to be set/reset.
Also, make the size of the exported image independent from
the current window size.

When multiple profiles were exported, for every exported image
the profile-widget was switched to/from print mode.
Move this out of the loop, i.e. initialize and reset the profile
only once. This should slightly speed up export, but not by a lot,
since most of the time is spent by compressing the PNGs.

The exportProfile function uses the UI and therefore was
supposed to be declared in backend-shared/* but defined
separately for desktop and mobile. Currently, only the
desktop version exists.
The goal however should be that there is no need of the
UI for this function. In a first step, move the function
to the common backend-shared/* code and conditionally
compile for desktop. In upcoming commits, the function
will be made independent of the UI.

This one is rich: when changing to profile-mode, the calculated
tissues are set according to the prefs.calcalltissues flag.
The DiveCalculatedTissue::setVisible() function ignores the
parameter and insteads sets the visibility according to the
expression "prefs.calcalltissues && prefs.calcceiling".
This is because the function is also called by signals,
which provide the wrong parameter.
Pass the correct parameter in the first place. Remove the
crazy signals and the overridden setVisible() function,
which ignores its parameter, later.

Currently, setting the visibility of chart features is a mess. It
is done when switching to the profile state and then via signals,

To enable grouping by trip in the statistics module, split
