Therefore, move the setting of the visibility up to the

On deletion of a single or multiple pictures, the whole DivePictureModel
was repopulated, which was clearly visible in the UI, owing to the
reconstructing of all images in the profile plot.
To avoid this vexing behavior, implement proper deletion routines in
DivePictureModel and ProfileWidget2. Since this needs sensible erase()
semantics the QList<PictureEntry> member of DivePictureModel was
replaced by a QVector. A QVector should be the default anyway, unless
there are very specific reasons to use a QList (which actually is
a deque, not a classical linked list).

The function removePicture() had a flag "last", which would indicate
that the called had finished removing pictures. Only then would
the model be recalculated.
This is a strange interface and, matter of fact, the caller was buggy:
if the last picture to be removed didn't have a proper url, removePicture()
was never called with "last" being set.

In MainWindow::current_dive_changed() first plotDive() is called,
which replots all the pictures by calling plotPictures(). This
is pointess, because it plots the pictures of the previous dive.
Then, updateDiveInfo() is called, which resets the dive pictures
and automatically replots them. Thus, switching between dives
both with hundreds of pictures is way slower than necessary.
Switching the plotDive() and updateDiveInfo() calls doesn't work.
The reason is not 100% clear, but it doesn't make sense to plot
pictures of the new dive as long as the profile still shows the
old dive anyway.
As a quick-fix, add a flag to plotDive(), which tells the function
to clear the pictures list instead of redrawing it.
Ultimately, plotDive() should probably be split in two functions.
One for the callers who update the pictures themselves and one
for the others.

The recent simplification of the close button code introduced a crash:
Deletion of pictures caused an invalid memory access, because the
CloseButtonItem was deleted with the parent DivePicture item.
For some (not fully understood!) reason, a reference to this button
was stored in the depths of Qt.
Empirically, it was found out that removing the first line of the pair
QGraphicsItem::mousePressEvent(event);
emit clicked();
fixed the crash.
It seemed therefore prudent to remove the whole questionable signal/slot
mechanism and directly call the removePicture() function of the parent.
Thus, the intermediate DiveButtonItem class became unnecessary and was
removed, leading to a shallower class hierarchy.
Unfortunately, CloseButtonItem must still be derived from QObject owing
to the Q_PROPERTY machinery, which is in turn needed for animation.
To make this compile on mobile, the conditional compilation of
removePicture() (#ifndef SUBSURFACE_MOBILE) was removed. After all,
if DivePixmapItem is used, there are pictures, so removePicture()
should be functional. Conditional compilation should concern the
whole class, not only this function.

This provides for reading of divemode change events from dive logs
and for writing them to dive logs. This applies to xml and git
divelogs. Divemode change events have the following structure:
event->name = "modechange"
event->value = integer corresponding to enum dive_comp_type (dive.c),
reflecting the type of divemode change (OC, CCR, PSCR, etc).
In the dive log file, the event value is written as a string that
corresponds to each of the enum values, e.g.
<event name='modechange' divemode='OC' />
This xml is also read from the dive log file and translated to an
appropriate value of event->value.

fake_dc() used to return a statically allocated dc with statically

All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does

The settingsChanged() function of the profile widget tries to be
clever and tries to prevent not needed replots of the profile.
I'm not sure this is very relevant in the first place as change
of settings are almost instantly, with or without replot. It
appears that replot is always executed when there are
calculated ceilings visible. But without calculated ceilings
a replot is "optimized out". This does, however, introduce dangling
divehandles in PLAN/EDIT and ADD mode of the profile, when
any setting that influences the y-axis is changed.
The fix is trivial. Just force a replot in the PLAN/EDIT and ADD
modes.

This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.
Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that. It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.
I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive. The end result looks messy as hell, but what did
you expect?
HOWEVER.
The only way to do this sanely was
- actually make the "struct plot_info" have all the cylinder pressures
(so no "sensor index and pressure" - every cylinder has a pressure for
every plot info entry)
This obviously makes the plot_info much bigger. We used to have
MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
code made that 8 be 20. That seems questionable. But whatever.
The good news is that the plot-info should hopefully get freed, and
only be allocated one dive at a time, so the fact that it is big and
nasty shouldn't be a scaling issue, though.
- the "populate_pressure_information()" function had to be rewritten
quite a bit. The good news is that it's actually simpler now, although
I would not go so far as to really call it simple. It's still
complicated and suble, but now it explicitly just does one cylinder at
a time.
It *used* to have this insanely complicated "keep track of the pressure
ranges for every cylinder at once". I just couldn't stand that model
and keep my sanity, so it now just tracks one cylinder at a time, and
doesn't have an array of live data, instead the caller will just call
it for each cylinder.
- get rid of some of our hackier stuff, like the code that populates the
plot_info data code with the currently selected cylinder number, and
clears out any other pressures. That obviously does *not* work when you
may not have a single primary cylinder any more.
Now, the above sounds like all good things. Yeah, it mostly is.
BUT.
There's a few big downsides from the above:
- there's no sane way to do this as a series of small changes.
The change to make the plot_info take an array of cylinder pressures
rather than the sensor+pressure model really isn't amenable to "fix up
one use at a time". When you switch over to the new data structure
model, you have to switch over to the new way of populating the
pressure ranges. The two just go hand in hand.
- Some of our code *depended* on the "sensor+pressure" model. I fixed all
the ones I could sanely fix. There was one particular case that I just
couldn't sanely fix, and I didn't care enough about it to do something
insane.
So the only _known_ breakage is the "TankItem" profile widget. That's
the bar at the bottom of the profile that shows which cylinder is in
use right now. You'd think that would be trivial to fix up, and yes it
would be - I could just use the regular model of
firstcyl = explicit_first_cylinder(dive, dc)
.. then iterate over the gas change events to see the others ..
but the problem with the "TankItem" widget is that it does its own
model, and it has thrown away the dive and the dive computer
information. It just doesn't even know. It only knows what cylinders
there are, and the plot_info. And it just used to look at the sensor
number in the plot_info, and be done with that. That number no longer
exists.
- I have tested it, and I think the code is better, but hey, it's a
fairly large patch to some of the more complex code in our code base.
That "interpolate missing pressure fields" code really isn't pretty. It
may be prettier, but..
Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.
Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.
Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:
- the momentary SAC rate coloring for dives will need more work
- dive merging (but we expect to generally normally not merge dive
computers, which is the main source of sensor data)
- actually taking advantage of different sensor data from different
dive computers
But most of all: Testing. Lots and lots of testing to find all the
corner cases.

Now that the cylinder pressures are more generalized, we should show
them even for non-CCR dives if we have them. The most notable example
would be having separate pressure transmitters for both cylinders in a
sidemount setup. The code no longer really depends on any CCR logic.
NOTE! This is still preparatory work, in that this is one part of
supporting multiple simulataneous cylinder pressures, but we are still
lacking in other departments (eg properly filling those fields in when a
dive computer exports multiple pressure sensors etc).
