d0beae59f9 profile: start with "absolutizing" the profile layout
The chart items were laid out in relative terms with respect
to a fixed scene size (100.0, 100.0). This simply does not
cut it when resizing the chart. Why should the axes always
occupy the same fraction of the chart independent of the size.

Moreover, this led to basically unmaintainable code.

Resize the scene according to the viewport and do
absolute placement of the items. This breaks the layout,
but at least now we have a chance to fix things
somewhat reasonably.

f713858ba4 profile: rename printFontScale to dpr (device pixel ratio)
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.

01983c65c3 profile: pass fontPrintScale at construction time
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.

The commit is larger than I had hoped for, but this makes
things ultimately less brittle.

0146a0c892 profile: remove displayed_dive from TankItem
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
plot. So the data can be extracted from there instead of
the global displayed_dive variable.

7da5719cab profile: set axis in constructor of TankItem
There is no point in a separate set-axis function if we never
change the axis anyway. Make the axis a const-reference to
show that it can never be changed.

47d673bda3 profile: remove TankItem's connection to the resize signal
Since the initial commit introducing TankItem, there was
a connection that replotted the item if the horizontal axis
sent the sizeChanged() signal. I never managed to create
this signal for the horizontal axis, only for the vertical
axes. Therefore remove this thing. If it turns out that
we need it after all, readd it in a more deterministic
way (i.e. call where it is needed).

27810f3217 profile: remove model parameter from TankItem::setData()
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".

fd23c3d908 Profile: don't crash when there are no cylinders
TankItem would happily access a non-existing cylinder and crash.
But freedives for example have no cylinders. Thus, handle that
situation gracefully by exiting early if there is no cylinder.

360f07e453 Cleanup: pass gasmix by value
In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.

Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.

Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.

This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

df156a56c0 Cleanup: replace virtual by override where appropriate
The keyword "virtual" signalizes that the function is virtual,
i.e. the function of the derived class is called, even if the
call is on the parent class.

It is not necessary to repeat the "virtual" keyword in derived
classes. To highlight derived virtual functions, the keyword
"override" should be used instead. It results in a hard compile-
error, if no function is overridden, thus avoiding subtle bugs.

Replace "virtual" by "override" where appropriate. Moreover,
replace Q_DECL_OVERRIDE by override, since we require reasonably
recent compilers anyway. Likewise, replace /* reimp */ by
"override" for consistency and compiler support.

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.

1d6683f3e0 Move Profile widget out of desktop-widgets
The reason for that is, even if profile widget is made with qpainter
and for that reason it should be a desktop widget, it's being used
on the mobile version because of a lack of QML plotting library that
is fast and reliable.

We discovered that it was faster just to encapsulate our Profile in
a QML class and call it directly.
