This was used to animate the position of the dive event items
when the size of the axis changed. However, that doesn't work
since quite some time. The axes size are changed when
1) switching dives
2) resizing the drawing area
In the first case, the dive event items are fully recalculated.
In the second case, animation speed is set to instant, since
resizing of windows is done continuously on any reasonably
modern desktop anyway. It might make sense on mobile, where
size changes are discontinuous, but there we use static
profiles anyway. Moreover, I checked a few applications and
none of them had animations when switching orientation of
my tablet.
Let's just remove this disfunctional thing and replace it
later, should someone complain.

The partial-pressure-axis was the only DiveCartesianAxis
child that had its own code to set the bounds. The bounds
of all other axes were set in plotDive().
For consistency, do this here as well. Thus, the whole
class can be removed.

The number of ticks was generated for each axis with custom
code. This code was not aware of the size of the profile and
could result in overly dense or sparse ticks.
Generalize the generation of the ticks. For now, round tick
values to integers. In the future, try to use more "nice"
looking values as we do for the statistics tab.

Instead of a host of virtual functions, let the base class
(DiveCartesianAxis) do the formatting of the axis labels.
To do so, it needs to know how to convert the internal
representation (e.g. mm) into the displayed value (e.g. feet).
Moreover, this transformation has to be adapted when changing
the locale-setting, therefore do it for every plot() call.
The transformation itself cannot be a simple linear translation,
because we have non-absolute display units, namely °C and °F.
Thankfully affine transformations are enough though.
Only one custom formatter remains: the time axis. It might
be a good idea to remove the virtual function and do this
via a flag.
This is all done not so much for code simplification, but
because for a general layout of the axis labels, the
axis has to understand the values of the labels and not
only handle them as opaque texts.

Instead of calculating the label sizes of the axes when
relayouting the chart, calculate them at construction time.
To do so, pass the digits before and after the decimal comma
to the constructor.
This is not so much an optimization thing, but rather an
first stab at more general label rendering. Time, of course,
will always be an exception. But hopefully the remaining
values can be done more generally.
Note that currently this code is a total mess. For example,
the labels for the temperature axes are not converted to
F if needed. And therefore also not shown. This will need
some major rethinking.

This is bike-shedding: Instead of two setMinimum()/setMaximum()
calls, use a single setBounds() call. A few axes (notably depth
and time) always have a 0 as lower bound. However, this will
change once there is a proper zooming functionality.

I doubt that this is necessary, but since most of the rest
of the profile code passes "isGrayscale" to "getColor()",
do the same here for consistency.
To avoid storing the isGrayscale flag, just create the pens
at construction time and store those.

The tissue percentages were realized as 16 independent polygons.
That didn't work at all with the new absolute scaling.
Reimplement the item and blast it onto a pixmap. Not only is
this artifact-free, it also should (hopefully) be quite a bit
more efficient than painting numerous lines.
In contrast to the old code, this does access the plot_info
structure directly instead of using the model. Not so much
for performance reason, but rather to make things more robust:
We have a strongly typed language. Why would we shoehorn data
through the weakly typed QVariant and mess with wierd
index-arithmetics. Makes no sense to me. Qt-model have to
be used for interfacing with Qt. They are terrible for
intra-application data transfer.

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.

The text and the brush are the two properties of text items
that change dynamically. To avoid complexities concerning
redrawing, set them concurrently instead of in two separate
calls.
Since setting one of the properties requires a full redraw,
there is no performance advantage in setting them individually.
This fixes a theoretical bug: the colors of axis labels were not
updated appropriately. However, it seems like value-dependent
labels weren't used anyway.

Alignment and scale of DiveTextItems are never changed. Therefore,
pass them at construction time. This makes things much easier
if we want to cache the rendered text [currently the text is
rerendered at every paint() event].
This also removes the "parent=0" default parameter of the
constructor, because inadvertently leaving out the last argument
led to a subtle bug.

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

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.

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 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.

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
variable. This makes no sense and allows for only one
depth axis. Make this a normal member variable that is
initialized in the constructor.
Also remove the settingsChanged() call in the constructor,
since this is a no-op (the depth unit is unchanged).

Original issue reported on the mailing list:
The ascent/descent rates are sometimes not what is expected.
E.g. setting the ascent rate to 10m/min results in an actual
ascent rate of 9m/min.
This is due to truncating the ascent rate preference,
then effectively rounding up the time to reach each stop to 2s intervals.
The result being that setting the ascent rate to 10m/min
results in 20s to ascend 3m (9m/min), when it should be exactly 18s.

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.
