No reason to keep this as a macro - a function is easier to
read, type safe and easier to debug. Moreover, give it the
more appropriate name "nearly_equal()". After all, it precisely
does NOT check floating points for equality.

With all the recent changes, some of the previous assumptions about the scale
of items seem to be no longer appropriate. Now that we are showing the icons in
the profile again on device it's quite obvious that they were way too big -
clearly we don't need the special scaling anymore.
Also implement a suggestion from Berthold to get slightly smaller fonts and
finer structures in the profile on mobile devices. This scaling of the DPR
seems to work well in my tests.

For reasons I don't understand, the device pixel ratio was taken into account
twice. And as a result the transformation applied to the profile made us show
only the top left part of it - but enlarged (depending on the DPR).
This code fixes that problem by simply forcing the transformation used by the
painter to be the identity matrix. I worry that this could be wrong in some
situations, but for now it seems to fix the problem.

There is no more reason to render the profile in printMode.
DPR is also supported in normal mode.
Moreover, don't scale the DPR down by fontScale. If we
have to scale down the fonts, we'll have to do this
differently without squeezing the rest of the profile
features.

There is no user of this left, because the device-pixel-ratio
is now passed directly to the profile.

Rendering resets the size, which now recalculates the axes.
Therefore, plotDive() must be called. The callers were doing
the opposite: call plotDive() first, then draw().
To make it easier for the callers, present a single interface
that handles these subtleties.

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.

Since using separate profile-instances for print/export,
we never exit print mode. Therefore, the mode parameter
can be removed. This is a preparatory commit for passing
the printMode at construction time.

Not having to readjust the scale on-demand will make the
code distinctly simpler. Let's just pass it once.

Thus, we can keep the scale factor constant during existence
of the view. For now, this is simpler than adapting existing
text elements. We might want to make this more flexible later.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
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.

So far the profile operated on the global displayed_dive. Instead,
take the dive to be displayed as a parameter to the plotDive()
functions.
This is necessary if we want to have multiple concurrent
profile objects. Think for example for printing or for mobile
where multiple dive objects are active at the same time.

This model is only needed when in plan mode. To enable multiple
profilewidgets at the same time (e.g. for the mobile app or
for printing), make the pointer to DivePlannerPointsModel a
member variable that is initialized at construction time.
Moreover, allow passing null as the DivePlannerPointsModel,
in which case planning will be disabled. This will be useful
for simple printing.

If a dive changes, we should simply redraw the profile. This could be
improved by checking for the fields that might impact the profile at
all, but this is definitely a step in the right direction.

The compiler complains that members were initialized out-of-order.
Even though this is not an issue here it is correct to emit a
warning, since only then it is guaranteed that the objects are
destructed in reverse-order with respect to construction.

If the user is scaling out again we need to make sure that our offsets
are adjusted so that we always show a subset of the profile and not
'empty space' outside of it. Instead of reimplementing the offset logic,
let's just trigger another paint() call.
This requires a trampoline function because of different signal and slot
signatures.

When zooming and panning the profile, make sure we always show a subset
of the profile and don't end up showing the empty space outside of the
profile.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
This will seem too small to many - it's pushing it, but it leads to a
significantly less cluttered profile, and we now have the zoom capability for
readability.
I think this is a nice improvement.

This property is used to render the profile of a given dive.
Weirdly, even though the diveId is an integer, it was stored
as a string. It is not clear why that is the case. Therefore,
turn into the more natural int and avoid unnecessary conversion.

Move the declarations of the "report_error()" and "set_error_cb()"
functions and the "verbose" variable to errorhelper.h.
Thus, error-reporting translation units don't have to import the
big dive.h header file.
