While analizing the code for the mouse movement I've discovered that
we did a lot of uneeded things: Set the color, the pen, the size
of a fixed-colored line, twice.
We also deleted-newed the same Pixmap / Text for every mouse movement
so now we reuse the 'entryToolTip' that consists of a huge line and
a pixmap, and after that we add the other tooltips that are not static
Also, reduced a lot the number of calls to expand() (that did a lot of
math).

Strangelly, this method was being called even if the rectangle was the
same, so we deleted everything and recreated everything again. tsc tsc.
Some more improvement is needed but we are getting there.

Very often the rectangle of the ToolTip doesn't need to change but we were
calling and firing an animation for it for *every* mouse movement, even
when we didn't really needed it.
Now it will only fire something if the rectangles are indeed different.
From my tests we reduced the number of calls to the animatior by about 20%
using a real divelog as test.

This is an attempt to make fewer calls to alloc functions when the mouse
is moving.
We were creating a membuffer, filling it (malloc / realloc), then freeing
it just after use. but we could simply hold that allocated area and reuse
it again.

The QPainter and the QPixmap were being created but never freed. A QPixmap
and a QPainter don't need to be created by new, they can be safely created
on the stack.
So, create them on the stack, pass them via const-reference
and use them correctly.

After looking with great care at the result of the mouse movement
on the profile, and also playing a bit with callgrind I've found
out that one thing that we were doing wrong was the way we looked at the
items in the scene, by calling scene()->items with
Qt::ItemIntersectsShape, our shapes are very complex curves
with thousends of points and we have lots of them. and it usually
doesn't matter because *most* of the time we are getting the
tooltip information from 'get_plot_details_new', so no accessing
to items was necessary.
By changing the access from Qt::ItemIntersectsShape to
Qt::IntersectsItemBoundingRect we had a speedup of almost 500x in a
section of code that's very important, and the good thing, nothing bad
happened because one of the only things that we are using this code is to
get information from the events, not the curves.

This patch introduces a new structure holding partial pressures (doubles in bar) for
all three gases and a helper function to compute them from gasmix (which holds fractions)
and ambient pressure. Currentlty this works for OC and CCR, to be extended later to PSCR.
Currently the dive_comp_type argument is unused.

Q_FOREACH will expand and already creates a copy of the
contained container, so this is just a waste of cpu cycles
and also increases a tiny bit the memory consumption.

The QGraphicsView system moves every selected item when the user
clicks and drags one. This patch makes a cache of all selected
items and removes the selection on them. When the user stops dragging
the Notification, the selection is restored.

By simply storing the coordinates based on the scene (instead of trying to
map them to real coordinates) the overlay position is correctly restored.
Also remove the redundant positioning before readPos is called.
