This patch just cleans a bit the Cartesian Axis, we never used
ticks on it, just the grid lines ( that I need to animate a bit. )

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.

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.

Now we can create an axis that's topToBottom, BottomToTop, LeftToRight and
RightToLeft.
This was needed for the Temperature Plot, because it should be inverted
(starting on the bottom).

Added the Temperature Graph with its related classes. A Temperature Axis
is also created so the item is plotted on the right place.
Currently the Temperature Axis is just like the depth axis - top is
zero, wich means that the graph is inverted.
Also, the Temperature axis is being displayed as this helps debugging.

The code for this item is a bit too big to be just the grid
of the dives and I know that, don't bully me. :)
The main idea of this grid is that it knows when it should be
updated. this is a bit different than the old code where all
the painting happened on the same method. This is bad because
it's more code, but it's better because if I break the grid,
only the grid will be broken, and it's easyer to spot the breakage.
in the old code if I did the wrong thing with the graphics context,
the whole graph gots messed out.

This is just to make it more obvious when new issues get introduced. The
build should always be free of warnings...

Another futile attempt to cleanup the code and make coding style and
whitespace consistent. I tried to add a file that describes the key points
of our coding style. I have no illusions that this will help the least
bit...
This commit should ONLY change whitespace

Created a Time Axis based on the CartesianAxis that knows
how to plot the minutes. This is needed because the CartesianAxis
donesn't knows about minutes at all, and would plot the
seconds instead.

The CartesianAxis used a simple method to put things on screen
which is wrong for almost any case besides the 'current value here'
since we store things in milimeters on the axis, we need to convert those
to meters before showing on the profile.

When we prepare the axis to show something on the Profile
we need to add the remaining ticks to show on screen,
Since this method tries to animately move / remove things
before calling this.
This has no animations yet - will have in the future.

If the size of the Axis changed, this should move them smootly to their

This patch makes the updateTicks method not remove / readd everything
when it's triggered, but to only remove the ticks / labels that
are no longer needed on the current display.

This is the same class as the Ruler, but uses the DiveLineItem
and DiveTextItem classes created to make it animateable. The next
few commits will work on that part. The Ruler was a very bad
name for a class that's actually an Axis, that's why I depreceated
the later.
