We also need to actually fill the model store with the cylinder models
we have in our dive lists to begin with.
This makes it all *trivial* to add a new cylinder model: just use a new
description, fill in the size and working pressure, and you're done.
The type automatically gets filled in, unless that description already
existed (in which case we leave it alone).

If the output units are set to cuft and psi, then we should show the
cylinder size and pressure properly.
NOTE! In the absense of pressure data, we *always* show the cylinder
volume in liter. There's no way to convert it to imperial units, since
the imperial units are not in physical size, but in air volume
normalized to surface pressure..

We used to have the heuristic that if we saw a cylinder working
pressure, then the cylinder size would be in cuft. Which meant that we
couldn't export our working pressures, because it would mess things up
on import.
But working pressure is actually nice to know, if you ever work with
cylinders in imperial units. So now that the import is fixed, add the
working pressure to the export.

That just screws up the good xml files that have everything in
well-defined units and chose the sane metric units.
So do the cuft -> liter conversion only if the input units are
explicitly CUFT, or known ambiguous input (SUUNTO).

It seems to be sufficiently useful to be worth updating the dive
information now.
This still doesn't handle multiple cylinders in any way. I need to
think about the interface for that.

Not quite there yet, though. And never mind multiple cylinders..

This doesn't actually change the cylinder type info in the dive, because
it's too broken for that. Instead it prints out what it would change
things to.
The gtk2 notion of text input focus is *really* odd. Why is the
cylinder type sometimes selected, and sometimes not?

Make it about general equipment management, and start hooking up
functions to show new equipment information when changing dives (and to
flush changes to equipment information for the previously active dive).
Nothing is hooked up yet, and it's now showing just one (really big)
cylinder choice, so this is all broken. But it should make it possible
to at least get somewhere some day.

Ok, so it's not connected to anything yet, and the tank choices (that

Instead of relying on our ad-hoc minmax finder, just use the local
minima/maxima information directly.

This way we can always find the actual min/max entry that generated the
local minima/maxima. Which is useful for visualization.

That seems to be the gtk2 way. Whatever. diveclog ends up defaulting
to metric units, because we all know that's the right thing to do.
However, I learnt to dive in the US, so I'm used to seeing psi and feet.
So despite the sane defaults, I want diveclog to use the broken imperial
units for me.

Dirk likes purple. I mean - Dirk REALLY likes purple.
And what's better than "purple"? You got it: "funky purple".
So this shows the one- two- and three-minute min/max information in some
seriously funky purple fringing. It's not really necessarily meant to
be serious, but it's a quick hack to visualize the data until we figure
out what to *really* do with it.

This turns the depth profile into a generic "plot_info" and calculates
minima, maxima and averages over 1-, 2- and 3-minute intervals for each
point. It also creates a smoothed version.
We currently don't actually show the results, but that's the next step..

I still think there should be some way to partition the space
automatically, but the algorithm that worked best was the simple

Which might as well be expressed as a loop.

The way cairo does scaling is really really inconvenient, and one of the
things in cairo that is fundamentally mis-designed.
Cairo scaling always affects both coordinates and object sizes, and the
two can apparently never be split apart. Which is very much not what we
want: we want just coordinate scaling.
So we cannot use 'cairo_scale()' to scale our canvas, because that
screws up lines and text size too. And no, you cannot "fix" that by
de-scaling the line size etc - because line size is one-dimensional, so
you can't undo the (different) scaling in X/Y.
Sad. I realize that often you do want to scale object size with
coordinate transformation, but quite often you *don't* want to.
Yeah, we could do random context save/restore in odd places etc, but
that's just a sign of the bad design of cairo scaling.
Work around it by introducing our own graphics context with scaling,
which does it right. I don't like this, but it seems to be better than
the alternatives.

This is a bit more natural, and makes it much easier to do scale
independence. In particular, I want to make it possible to grow and
shrink the graph, and this should make it particularly simple to react
by giving more or fewer minmax points.

Use start/end sample pointers to make a recursive algorithm possible.
Also, clean up the end condition - we don't want to return an
uninteresting minmax result just because we ran out of samples.

Just iterate over the dive list entries, updating them one by one.

This should take care of it all, unless I missed some case.
Now we should just save the default units somewhere, and I should do the
divelist update much cleaner (instead of re-doing the divelist entirely,
it should just repaint it - now we lose the highlited dive etc).

This shows the depth properly in meter or feet depending on unit
selection.
It also changes the horizontal depth rulers to be at 10m/30ft intervals
rather than the previous 15ft. With the textual depth markers, the
horizontal lines aren't as important any more.

This doesn't actually *do* anything yet, but it introduces the notion of
output units, and allows you to pick metric or imperial.
Of course, since the output doesn't currently care, the units you pick
are irrelevant. But just wait..

The UEMIS Zurich SDA keeps recording samples for quite a while after the
dive ended. These provide no additional information, but confuse our
drawing algorithm as they can cause us to draw both the depth and tank
pressure plots beyond the right edge of our canvas.
Stop drawing if sample->time.seconds is larger than dive->duration.seconds.

Most developers on GitHub are not used to projects that use the Signed-off-by convention.
They do, however, tend to read the READMEs to see which conventions the author prefers
to follow. If you are explicit about what you prefer in the README with easy to follow
instructions, it is more likely people will follow those conventions.
