This patch makes use of a cache variable instead of creating / accessing a
new one via operator[], because for some reason QGraphicsPolygonItem
doesn't return a reference for polygon and a copy is always made.

This patch optimizes a few items when hitting the
'save preferences' dialog, since when a preference is
modified, all the items try to reload their visual
based on wether a preference changed or not, the correct
code for 'hey, my pref changed, let's update' needed
to be done.
now the axis will only set a new maximum if it's different
from the old one ( and thus, going to a new dive with
the same maxdepth or maxtime as the old one will not touch
their axis, not triggering gratuitous animations. )
also, the 'incr by 3m' was not being called - it seems
that our 'syncsettings' method is not storing things on
the 'prefs' global var. I added just for the incr by 3m
case, but it's something that we need to check later.

Created a method to check if calculations should take place
taking into consideration what changed on the model. if the
model changes *everything*, them, all calculations should
be done, but if just some of the columns of the model are
changed, only those columns should trigger an visual update
on the items.
In theory this patch looks right, but something is wrong (
calculations are not being made. ), so I'll commit this any
how, and fix on the next commit.

This commit is rather big, and I forgot to cut it in pieces.
The first part creates a new 'calculate_gas_information' that will not
fill the profile_info->maxpp member ( that should be removed from it as
soon as the new dialog is finished ). The reason for that is that all of
the profile data will be calculated and the graph needs to update
dynamically, so whenever the settings changes, I ask for the model which
is the biggest graph and replot only the ones we need.
The second part adds a new animation function 'animdelete' to fade-out and
delete the item when it's done. the old function 'hide' did just that but
a hide shouldn't delete anything.
The third part is preferenes awareness for the PP graphs. I created two
new functions that receive the settings key for visibility and use the
QSettings to show / hide them. This also works quite well for the axis;
if no graph is visible, the axis will also hide itself.
The fourth part is colors. The pp graphs now have the correct colors.
And a bit of code cleanup too.

This makes the beginning of the partial gas pressures, there's
two more. but this code uses a good part of the Model View system,
and it's way clearer than the old one. Luckly the other 2
missing items will be even more clear ( the diffs ) to do,
because I just need to create a new PartialPressureGasItem and
set the properties. <3

This patch prevents memory leak by adding the text on the list of

Dirk's implementation of the MeanDepth item was correct, but in order to
add the 2 strings to it ( one at the begin, one at the end ) I had to put
more stuff inside the ProfileWidget that's already packed with graphics
items.
So I created a new class MeanDepthItem that contains these 2 strings and
will get updated whenever the value changes.
I also fixed a math inconsistency where I changed RIGHT to LEFT.
(wich fixed a few text-placements, and broke others.)

When the preferences changed signal is fired, the items that can change
their visual based on the preferences now have to reimplement the
preferencesChanged method, so they know if they need to be replotted on
screen. I already implemented that for two of the items ( ProfileDepth and
Ceiling ) but others might need that too.

This code actually uses the preferences for something. It will show and
hide the calculated ceiling in red if the prefrerences are changed for
that. One bad thing that I did in this commit ( so it was easy to try ) is
that a preference change will redraw the whole graph - not optimized. I'll
make this better in a later commit so that only the affected items will be
redrawn.

This is an attempt to speed up painting a bit. Since we will draw the red
ceiling on top of the profile, I don't see a reason to dig a hole in it,
creating an more complex shape to be passed to the painter. Easier shapes
are easier to draw. ( I think )

This just adds the texts for the gas profile. I've also added a method on

the other methods can use it.
This code is almost 1-to-1 with the old one, a bit of thinkering can be
used to merge this loop with the upper one.

Currently the Temperature Axis is just like the depth axis - top is

The DiveProfileItem contained much of the complexity and
algorithms for almost all line-based items on the canvas,
so I transformed that to a general abstraction and implemented
a new DiveProfileItem that uses it. this should reduce a
bit of code since the implementation of the PP Graphs, Temperature
Cylinder Pressure and maybe a few others will only need to
reimplement the paint() and the modelDataChanged() methods.
The rest is ready.

I've used the paint() method on it ( even if it's not necessary
on a QGraphicsView ) to reduce absurdely the number of items that are
inserted on the QGraphicsScene ( each small line of the profile should
be an item if it was not for this, it's like that on the old profile. )
and thus reducing the memory consumption, speed and so on.
