Make pressure plot shading by sac rate consistent
Some parts of the existing code used the depth at the time of the sample
to calculate the sac rate - it makes much more sense to use the average
depth. But that requires us to loop over the entries and average the
individual sac rates per segment instead of just using the beginning and
end depth of the multi-segment interval we use for smoothing purposes.
This may seem like a subtle detail, but it does in fact matter when we
plot the synthetic tank pressure values that we create when we have no
tank pressure data in the samples.
Another detail we change here is to not artificially start with a forward
looking segment of the full SAC_WINDOW but instead just start with the
first two data points and then simply let the time window grow until it
hits SAC_WINDOW - at which point it becomes a sliding window.

Color pressure plot according to current SAC rate
Similar to color indicating vertical speed in the profile plot we now use
color in the tank pressure plot to indicate current SAC rate.
We use a 45 sec sliding window to make sure we cover at least two breaths
for each current SAC sample to avoid artificial oscillation based on
breathing rhythm for corputers with high sample resolution.
Not sure about the color coding that I'm using right now - it's green-ish
for SAC rates under 15l/min ~= .55cuft/min and turns yellow and red as you
go higher. That seems to work well for me, but for other divers this may
be way off (or at least not as useful). Maybe this should be configurable?
This is a lot more diver specific than the vertical velocity where there
are clear recommendations based on safety considerations on what is good
and bad.
As a side effect, this removes the color coding that showed you whether
you were looking at pressure data from samples (green) vs. interpolated
pressure data (yellow). Not sure if people really want to see that. We
might be able to indicate this differently (I am thinking different line
width or transparency or something along those line)

Lubomir's solution to fill them with a newline doesn't work. Well, it

So this is a third approach: if we reset the text to empty, first set it

at least one version of gtk, and doesn't have the problem with the space
