The DiveTextItems were redrawn on every paint() call. This was
a prohibitively expensive operation (converting the text into
a path, drawing an outline, etc.), which was called numerous
times.
Instead, render the text only when changing into a QPixmap
and blit that pixmap in the paint() call.
This will make it possible to do absolutely positioned
DiveTextItems. So far they were placed relatively in
scene coordinates ranging from 0-100(!).

The text and the brush are the two properties of text items
that change dynamically. To avoid complexities concerning
redrawing, set them concurrently instead of in two separate
calls.
Since setting one of the properties requires a full redraw,
there is no performance advantage in setting them individually.
This fixes a theoretical bug: the colors of axis labels were not
updated appropriately. However, it seems like value-dependent
labels weren't used anyway.

Alignment and scale of DiveTextItems are never changed. Therefore,
pass them at construction time. This makes things much easier
if we want to cache the rendered text [currently the text is
rerendered at every paint() event].
This also removes the "parent=0" default parameter of the
constructor, because inadvertently leaving out the last argument
led to a subtle bug.

To layout the profile we need to determine the height
of texts. Add versions for a DiveTextItem and a static
function, which is passed the scale and dpr. The latter
is used to setup items, where we do not necessarily
have a text at creation time (e.g. the tankbar).

To properly layout the profile we need to know the expected space
required by the vertical axes. In the general case, format the
the text "999". For the partial-pressure-axis, use "0.99".

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.

Since there (currently) is no interactive widget on mobile, there
is no point in compiling it. This was a bit more complicated than
expected, since there were other source files (divehandler.cpp
and ruleritem.cpp) which reference ProfileWidget2 and therefore
need to be removed. Otherwise, the dreadful MOC produces unresolved
references.
We could now remove all the conditional compiles in
profilewidget2.cpp, but let's keep them for now. We might have
to readd a number of them later, when making the mobile-profile
interactive.

Instead of using the interactive ProfileWidget2, just
use the ProfileScene to render the profile for printing,

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

The font print scale is now set once on construction and this

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
can access it directly instead of testing for printMode.
Since the DiveTextItem is not updated using signals anymore,
the connected flag can be removed.

The constructors of Time- and TemperatureAxis don't do anything.
In reasonable modern C++ we can simply reuse the constructor

Thus, we can keep the scale factor constant during existence

The current way of handling the "print scale factor" is
complex: The text fields are added and later resized via
signals. Things could be simplified by just redoing the
chart when changing the scale factor.
Moreover, in the future we will want to adapt the size of the
axes depending on the size of the texts.
As a first step, factor out the creation of the profile-widget.
This can then be used to recreate the profile when changing
the scale factor.

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.

a follow-up commit, the signals can be removed.

The plan is to simplify the visibility-control of non-interactive

This adds the menu item to rename a dive computer (ie create a nickname

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.
