Remove warning about item not on the scene.

This patch fixes a warning about the QGraphicsItems not being on the
QGraphicsScene, and thus, cannot be removed from it.

Remove warning about a null pixmap.

Since I didn't add a pixmap to be the background of the new profile, yet,
things got wrong on mac and crashed. This should fix it.

Added the Cylinder Pressure Axis

The cylinder pressure axis is the 'Y' axis for the Cylinder plot.
I positioned it in around 20% to 60% of the screen state.

Add Information about the Pressure to the Model.

Added missing information about the pressure to the model; this shows that
I didn't do something right, as the model has 0 pressure information. Need
to fix that on the next commit.

Create a version of create_graph_info that doesn't depend on GC.

This version of the create plot info is the same as before, with the
difference that it doesn't depends on the gc.
Also fixed a crash.

The Pressure Index, Information and interpolated seems wrong,
I'm getting only zeroes.

Add the gas pressure plot.

Added the Gas Pressure Graph with the related Model Changes
to access the cylinder index, pressure, interpolated pressure
and SAC.

The plot does not correctly plot its color right now but it's not hard to
do.

Plot the Temperature Text.

I Moved the 'plot text' method of the Old Graphics to the new
layout - this one was mostly unchanged as it was already good
as is.

And used the TemperatureProfileItem to also display texts.
This was the first implementation of the new system that uses
*less* code than the original one, wich makes me happy.

Fix maxdepth in new profile

get_maxdepth() already gives you the correctly rounded maximum depth.
Don't mess with it.

Add mean depth to new profile

With massive hand-holding by Tomaz.
Writing for the new profile code is slightly different. You don't draw
anything, you just tell the widget where things are supposed to end up and
how they are supposed to look. Really nice.

Stop doing the (very expensive) pow() calculation pointlessly

This re-organizes the saturation calculations to be in my opinion
clearer: we used to have the "one second" case completely separate from
the "generic interval" case, and this undoes that.

It *does* keep the special static cache for the one-second buehlmann
factors, and expands that with a *dynamic* cache for each tissue index
that contains the previous value of the buehlmann factor for a
particular duration.

The point is, usually we end up using some fixed duration, so the cache
hit ratio is quite high.  And doing a memory load from a cache is *much*
faster than calculating exponentials.

Ignore mouse wheel events on tags widget

This prevents tags widgets (dive tags and buddy) from grabbing
focus on mouse wheel events but allows entering dive edit mode
on mouse click.

It was attempted earlier by Dirk (commit d117beca), but edit mode
did not work properly.

Use focus policy setting from widget constructor

Since we use tags widget for several input fields (tags, buddy,
divemaster), it makes sense to keep focus policy setting in one place.

Remove the plotText function, standardize with the TextItem.

Removed the plotText function and replaced it with the
DiveTextItem class - this way there's just one way to add
text on screen, and it also makes it easy to fix positioning
of stuff there. Which is what I'll try to fix on the next commit.

Fix the positioning of the Labels using the new DiveTextItem

This uses a combination of items on the canvas which makes it easier to
position it where I want.

This also broke the other texts because I forgot about them. I will
fix that on the next commit.
