This was requested on the mailing list. Reduce code size somewhat
by deriving the binner and the variable classes from common
base classes with a mean-vs-max flag.

This workflow will download the current snaps published in the `candidate`
channel for all architectures and check them for packages with published
Ubuntu Security Notices. If it finds one, it will trigger a build of the
snap recipe:
https://code.launchpad.net/~subsurface/+snap/subsurface-stable
This will rebuild the snap with patched packages and publish it to the
`candidate` channel.

The grid is based on the axis ticks. If labels in histogram
axes were skipped (because there are too many bins), it could
happen that the grid was incomplete, because the first and/or
last tick were missing. Add these explicitly.

The info box was placed either above or below the mouse-pointer.
If the pointer is at the center and the infobox higher than
half the chart, it would cross the border. Detect this case
and place the info box at the center.
Same logic for right/left, though that should typically not
happen.

The coordinates of these were calculated when creating the feature.
This is wrong, because the min/max values of the axes can change
on resize to get "nice" number. Therefore, recalculate after resizing.
This means that the general "LineMarker" class has to be split into
two classes, one for regression lines and one for median/mean
markers.

Easy enough to implement, but one weirdness:
To get the height of the rotated text, one has to access the
width() member of the boundingRect. I'm not sure if that makes
sense, but so be it.

The bars were set to the z-value of the labels. Not an issue,

plot later. Still, do the right thing.

Since we want to get rid of QtCharts, we have to render our own

In the future we want to use our own axis implementation to
convert from/to screen coordinates. For this purpose, we
need to save the axes with the series. Especially if we want
to support multiple series on different axes.

The chart was passed as argument to the function recalculating
the axis labels. Instead, pass the chart in the constructor of
the axes and save it. This gains us flexibility for the future:
There will be more functions that need to access the chart (e.g.
resizing of the axes).

Checking a field that we intentionally don't store to disk is obviously
wrong. It's been this way for a long time and it has annoyed me many
times, but somehow I never spent the time to track down why this was
happening.
It makes much more sense to use the presence of either the don't check
flag or a next check date as an indication that we have already asked
this question.

It seems to make more sense to have it there with the 'Yearly Statistics'

Recently code was added to reset variable 1 binner if the second

We now have three different things that are kinda like statistics:
- the summary tab (reasonably useful when looking at selected dives)
- the yearly statistics (Ctrl/CMD-Y)
- the full statistics (Ctrl/CMD-T)
I'd argue that's at least one too many. But I'm sure some people will disagree.

A steep regression line would shoot out of the chart. Therefore,
clip to the y = minY and y = maxY lines.
QtGraphicsScene has its own clipping routines, but they are
very general, so let's do this trivial case by hand.

Dirk says rounded corners look better. This now looks a bit
extreme to me and probably the border size should be increased.

Factor out code from ProfileWidget's ToolTipItem, but make
the radius of the corners dynamic. Move into backend-shared,

The old ways was to select the chart first, then depending on
the chart choose the binning.
Willem says that it should work the other way round: select
the binning (or operation) and make the charts depend on
that.
I'm not arguing one way or the other, just note that the new
way is much more tricky, because it is easy to get unsupported
combinations. For example, there is no chart where the
first variable is unbinned, but the second axis is binned
or has an operation. This makes things distinctly more tricky
and this code still needs a thorough audit.
Since this is all more tricky, implement a "invalid" chart
state. Ideally that should be never shown to the user, but
let's try to be defensive.

Add a new "statistics" application state. In the statistics state
show the statistics widget and the filter in the top quadrants.
The idea is to allow filtering and doing statistics at the same
time.
Sadly, we can't use the filter-widget in different quadrants,
because Qt's ownership model is completely broken / inflexible.
It does not support a widget having different parents and
thus a widget can only belong to one QStackedWidget.
Hiding the map in the statistics view is quite hacky:
Since the view of the quadrants is not determined by the
"ApplicationState", we have to restore the original quadrant
visibility when exiting the stats mode. Therefore, set the
original visibility-state when changing application state.
The MainWindow-quadrant code really needs to be rewritten!

Implement a widget that shows the statistics state as comboboxes
and the statistics chart. Calls into the statistics code if any
of the comboboxes changes.
The hardest part here is the formatting of the charts list with
its icons and with headings. Sadly, it is not trivial to arrange
icons horizontally. Therefore we would have to fully reimplement
the ComboBox view, which is probably not fun.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Qt's comboboxes are controlled by models, there's no way around
that. To customize the chart-selection widget this must therefore
be abstracted into a model. On the upside, this hopefully can
be used for desktop and mobile.
The model provides icons and paints a warning-symbol on it
if the statistics core code deems the chart to be not recommended.
Notably, when plotting a categorical bar chart against a
numerical value (in such a case histograms are preferred).
Includes a fix for a silly oversight in CMakelist.txt: add the
statstranslations.h header.

Add a few icons representing chart type (in internal terms:
chart subtypes): bar (grouped, stacked, single), box-and-whisker,
data points, pie. These should be shown in the chart selection
box.
Yes, the "artwork" is not pretty, so see these as a placeholder.
Morover, add a "warning" icon. This icon already existed as SVG,

The StatsState structure fully describes the current state of
the chart: the selected axes, operations and additional chart
features, such as legend or labels.
The code implements sanity checks and reacts accordingly,
if an invalid combination of variables and charts is chosen.
The chart and variable lists to be displayed can be queried
and are encapsulated in the StatsState::UIState structure.
Some variable / chart combinations are possible, but not
recommended, which is represented by a warning flag.
