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 profile would reload for many settings-changed signals.
It didn't listen to the deco-info-changed signal, because
that had no effect (which seems to be a bug).
Since this flag should indicate whether the deco-info is
shown and therefore a change should replot the profile,
let's listen to the corresponding signal.

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
concept.

Instead of using the interactive ProfileWidget2, just
use the ProfileScene to render the profile for printing,
export and mobile. One layer (QWidget) less.
This removes all the kludges for handling DPR on mobile.
Thus, the rendering will now be off and have to be fixed
by redoing the scaling code.

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.

This simply subclasses QGraphicsScene and is used as

Instead of intializing the text fields and then changing the
font scale via signal-rigmarole, pass down the font-scale

Since the fontPrintScale is only set in print mode, we also

Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Very annoyingly, to render the profile for printing / export,
the profile still had to be show()n, thus requiring a parent
window.
Analysis of qmlprofile.c showed that this was due to the
transformation matrix not being properly set up on non-show()n
scenes.
Instead, we can simply render via the QGraphicsScene
(circumventing the QGraphicsView).
The code was factored out into the ProfileWidget2::draw()
function. This will hopefully make it easier to change
the size-code of the profile.

This one is rich: when changing to profile-mode, the calculated
tissues are set according to the prefs.calcalltissues flag.
The DiveCalculatedTissue::setVisible() function ignores the
parameter and insteads sets the visibility according to the
expression "prefs.calcalltissues && prefs.calcceiling".
This is because the function is also called by signals,
which provide the wrong parameter.
Pass the correct parameter in the first place. Remove the
crazy signals and the overridden setVisible() function,
which ignores its parameter, later.

Currently, setting the visibility of chart features is a mess. It
is done when switching to the profile state and then via signals,
when the preferences are changed.
However, when the preferences are changed the chart is replot anyway.
So let us simply set the visibility on chart replot. Then in
a follow-up commit, the signals can be removed.

The plan is to simplify the visibility-control of non-interactive
chart features. As a first step identify those features that
depend on preferences-flags and factor out the setting of their
visibility into a new function updateVisibility().
This commit effectively only reorders the setting of the
visibility and therefore should have not user-visible effect.

This adds the menu item to rename a dive computer (ie create a nickname
for it) when right-clicking on the dive computer name of a dive computer
that has a serial number (indicated by having a non-zero ->deviceid).
It is nonfunctional because it's really just the skeleton code: it needs
the UI to actually ask for a new nickname, and then it needs to actually
do the proper "create_device_node(model,serial,nickname)" to set it (or
remove the nickname if empty).

If the last displayed dive had events, those DiveEventItems had slots connected
that would update those icons if things changed. When closing the dive log and
switching to a different one, those slots were still called and would then access
freed memory (the event structure from that old dive that is long gone by then).
This code explicitly deletes those DiveEventItems which also removes those signal
slot connections.

When creating the context menu on the profile, the code has
to check whether the context menu is activated on the
dive computer name to show a special menu (delete / split
dive computer).
This was done by setting a special property on the item
and then checking for that property on the item that
the menu is invoked on or its parents.
The reason the code didn't simply check the pointer was
probably that DiveTextItem uses multiple inheritance:
It derives from QObject and QGraphicsItem. It has to derive
from QObject first, because (the ridiculously broken) MOC
needs it that way. The object added to the scene is a
QGraphicsItem. Thus, we get a pointer _into_ the DiveTextItem
object.
However, that's all completely unnecessary. We can simply
compare the pointers, as the compiler will understand that
QGraphicsItem is only the second base class of DiveTextItem.
Magic!
Let's remove the cruft and simply compare the pointers.
