d3a2c40f52 profile: remove "changed" flag of DiveCartesianAxis
This prevented the axes from being redrawn on resize. It shouldn't

efc89b9d9c profile: use dynamic distances between labels on chart
Use variable intervals for printing temperature and heart
beat labels. Obviously, so that the labels don't become
sparse on zooming, but also to make them not too crowded
on mobile / small screens.

This doesn't work for depth labels, because these labels
use data provided from the profile.c core that doesn't
know about the size of the chart.

2f9c0c04b5 profile: replace orientation by inverted flag
There were two somewhat redundant flags for the axes: the position
(left, right, bottom) and the orientation (up-down, left-right, etc).

Replace the latter by an inverted flag: if true, the axis is
up-down or right-left, i.e. the opposite of what one would expect
for a normal graph.

Set the flag in the constructor and remove the setOrientation()
function.

Sadly, the code is a bit complex, because screen coordinates are
top-to-bottom. Who thought that would be a good idea?

Note: this also fixes the placement of the ticks of the time
axis.

3a79f3e78a profile: set textColor in constructor of DiveCartesianAxis
There were virtual functions to calculate the label colors
based on the value of the label. However, these functions
only returned constant values. Therefore, just set these
in the constructors.

Thuse, a few virtual functions and derived classes can be
removed.

7bc90b6dfe profile: set visibility of text and lines in constructor
The visibility of axis text / lines is never changed, so set
in axis constructor.

Moreover, instead of rendering the lines/text and then setting
them invisible, do not render them if invisible.

The whole thing appears superfluous, since the proper way to
not show lines/text is to just not call updateTicks on the
axis. But in the future we might want to have axes with text
but no lines, so keep for now.

Since this means breaking out the text / line rendering
into their own function, we might rename some variables to
make them (at least somewhat) more clear.

a7a7bd182e profile: special case time axis
Rounding the axes dimensions to "nice" number may have been a
good idea, but for the time-axis it feels weird.

Therefore revert the time axis to the previous behavior:
range is set according to the data. To differentiate between
time an other axes, use the position: the time axis is the
only axis at the bottom. Yes, that's ugly but pragmatic.

Since we have that flag also use it for the special casing
of the text-display. Spares us one virtual function dispatch.

99c4741508 profile: avoid double recalculation of tick positions
The ticks were recalculated twice per plotDive() call:
1) When updating the position of the axes in updateChangeLine()
2) After setting the bounds in plotDive() via setBounds()

Remove the first instance. updateChangeLine() is called in
only one place [from plotDive()] and therefore, the recalculation
is always redundant. Moreover, rename the function to setPosition(),
since it doesn't do any animation at all.

b0faf2e4b1 profile: remove DiveCartesianAxis::sizeChanged() signal
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.

0de40a85b7 profile: generalize tick generation
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.

values to integers. In the future, try to use more "nice"
looking values as we do for the statistics tab.

177df72d33 profile: unify formating of axis labels
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.

322e2baa8d profile: calculate maximum label sizes on construction
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.

505e4e47eb profile: reimplement DivePercentageItem
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.

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.

766546fc19 profile: Add a DiveCartesianAxis::Position enum
To properly layout the axes, it is necessary to specify on
which side of the chart they are located.

There is already an "Orientation" enum. However, that gives
the direction (top-to-bottom, etc.), but not the position.
It might become obsolete in the future, since the direction
can also be expressed by setting min and max accordingly.

84ebd1d67a profile: pass print-mode add construction of ProfileScene
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.

of passing down the value to the respective functions, the

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.
