0c4e1697db Be more careful about unit changes
When we change units, we need to flush any currently active dive
information in the old units, and then carefully reload it in the new
units.

Otherwise crazy stuff happens - like having current cylinder working
pressure values that are in PSI because that *used* to be the output
unit, but then interpreting those values as BAR, because we changed the
units.

Also, since we now properly import working pressure from Diving Log,
stop importing the (useless) cylinder description.  The Diving Log
cylinder descriptions are things like "Alu" or "Steel".  We're better
off just making up our own.

Finally, since Diving Log has cylinder size in metric, make sure that we
do the "match standard cylinder sizes" *after* we've done all the
cylinder size conversions to proper units.

61d0aa10e1 Parse 'Diving Log' cylinder working pressure
Oh Gods. Why are all other scuba programs so f*&% messed up?

The Diving Log cylinder working pressure is in bar - which is all good.
But their pressure *samples* are in PSI.  Why the h*ll do people mix up
units in the same damn file like that? I despair at the pure
incompetence sometimes.

I suspect the pressure samples aren't "really" in PSI: they are probably
in some user-specified units.

d1b30212ff Add more static cylinder types - and pick them up from the dive log
This adds a few more predefined cylinder types to the static list, but
perhaps more importantly, if we try to show a cylinder description that
we haven't seen before, we automatically add that description to the
list as well.

This way, if people have their own cylinder types, our cylinder
management will automatically figure them out and make it easy to enter
them.

NOTE! It might be best to add the new cylinder description at dive log
load time, rather than at 'show' time.

1fe687a16c Add new cylinder models to the cylinder model store
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).

c43e1ad21b Let people manage their cylinders in cuft and psi
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..

b17c7f0709 Now that we don't mess up import, we can save the cylinder working 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.

ed4b739f5f Don't guess input cylinder size as cubic feet
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).

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

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.

a13d3172fa Save default units using GConf
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.

So this shows the one- two- and three-minute min/max information in some

d4a1dfb3d9 Fix up horribly broken cairo scaling
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.
