This flag existed for historical reasons: The base of bar items
had no line and therefore the lines had to be draw differently
for horizontal (base to the left) and vertical (base on the bottom)
item.
This did not work properly and therefore has been removed. Thus,
the flag became pointless.

When all items of a bar in a bar chart are selected, highlight them
by overlaying with a checkerboard pattern. A gray checkerboard seems to
work reasonably well, regardless of base color.

Allow the user to select regions of the scatter plot using

Unfortunately, the list-selection code is so slow that this

If we want to make bar charts selectable (when clicking on a
bar select the dives the bar represents), then we must store
the dives behind bars. Therefore, use dive-based bins instead
of count based bins in bar charts and pie charts. This gave
some churn because every structure where a count is stored
has to be changed to store a vector of dives. Try to use
move semantics where possible to avoid duplication of dive
lists.
On a positive note, the count_dives() function of the
binners can now be removed, since it is unused.

In TemplateLayout, there was a progress indication, which reported
the progress - not of the actual rendering - but of adding the
dives to the "to render" list. Which is of course done in less than
a ms, making the whole thing completely pointless.
Instead, emit progress when actually looping over the dives or
statistics.
Nobody ever noticed the problem because even rendering is done in
fractions of a second and indeed is accounted to only one fifth
of the total progress.
The real purpose of this "fix" is to get rid of the getTotalWork()
function, which was just insane. Instead of asking the TemplateLayout
how many dives it rendered, this number was extracted from
global state. Simply store the number of dives in the TemplateLayout
object instead.
Moreover, fix two coding style issues:
- "Page" variable identifier starting with a capital
- The Printer::render() being defined (as opposed to declared) with
a default parameter. This is not how C++'s default parameters work,
sorry.

The memory management of the quadrant widgets is a total mess:
When setting the widget, the QSplitters take ownership, which
means that they will delete the widget in their destructor.
This is inherently incompatible with singletons, which must
not be deleted.
To avoid all these troubles, remove the widgets from the
QSplitters in the desctructor of the MainWindow. This of
course means that we now have to take care about deletion
of the widgets.
For local widgets use std::unique_ptr, for singletons use
a static variable that is deleted on application exit.
Sadly, for the map widget we can't use a normal singleton,
because the QML MapWidget's memory management is buggy.
Add a comment in the source code explaining this.

When in planner mode, don't allow the user to change the application
state. This brought us nothing but troubles and inconsistencies.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
There was the "application state", which decided what to show
in the "quadrants" and the "view state" which decided which
quadrant to show. These interacted in a hard-to-grasp way.
The "view state" is used to show the map or dive list in
full screen.
I simply couldn't get these two orthogonal states to interact
properly. Moreover the thing was buggy: If a quadrant was hidden,
the user could still show it, by dragging from the side of the
window, at least under KDE.
To solve these woes, merge the two states into a single
application state. If the widget of a quadrant is set to null,
don't show it. So the four "view states" are now "application
states" where three of the four quadrants are not shown.
This also changes the memory management of the widgets:
widgets that are not shown are now removed from the QSplitter
objects. This makes it possible that the same widget is
shown in *different* quadrants.
While writing this, I stumbled upon a Qt bug, which is known
since 2014:
https://forum.qt.io/topic/43176/qsplitter-sizes-return-0
When restoring the quadrant sizes there was a test whether
the quadrant size is 0. If that was the case, a default size
was set. This seems not to work if the widgets were recently
added. Since this test now always fails, make the quadrants
non-collapsible and thus guarantee that 0 is never saved as
a size.

When reparenting the statistics widget, QtQuick deletes
the rootNode and all the child nodes. It is unclear whether
this is a bug or intended behavior. In any case, it means
that the pointers to QSG nodes in the chart items become
stale.
To avoid this, delete all chart items in the root node's
destructor, before QtQuick can do anything. It is unclear
from which context this is called (render or UI) and whether
this is even valid. In some tests, it seemed to work.
The difficulty is that all the stale pointers to chart items
have to be deleted as well. All in all, the QSG memory
management is a big nuisance and very brittle.

Since we no longer show the noisy git updates to the user, it has become
harder for them to know whether a sync to the cloud was successful.
Since a manual sync will never show the new 'what did you change and
here's how you undo it' notification, it seems easy enough to simply
show a status update.
This adds a passive notification with no action button after the user

The updatePaintNode() function, which is run on the render
thread detected a geometry change and initiated recalculation
of the chart layout.
This means that plotAreaChanged() was called in two different
thread contexts, which is questionable. Instead, hook into
the geometryChanged() function and recalculate the chart items
there.
This fixes a rendering bug, because the old code would first
delete unneeded items and then rerender the chart. Thus, old
grid and tick items were still visible.
