This creates a helper function called "gas_volume()" that takes the
cylinder and a particular pressure, and returns the estimated volume of
the gas at surface pressure, including proper approximation of the
incompressibility of gas.
It very much is an approximation, but it's closer to reality than
assuming a pure ideal gas. See for example compressibility at

There is a bug in GTK 2.2x where the links in the about dialog
(and URI's in general) do not work on Windows. To solve that
we add the OS specific method subsurface_launch_for_uri().
But to dispatch URI requests from the about dialog we need to
set a hook either with gtk_about_dialog_set_url_hook() (which is
deprecated from 2.24) or using signals like "activate-link".
One problem with the "activate-link" signal thought is that
we need to have a reference of an about dialog to pass to
g_signal_connect(). So instead of using gtk_show_about_dialog()
let's manage a dialog ourself with gtk_about_dialog_new(),
gtk_dialog_run(), gtk_widget_destroy().
Other changes:
- for GTK _bellow_ (but not including) 2.24 use
gtk_about_dialog_set_url_hook()
- use g_object_set() which is a convenient replacement for
the varargs list in gtk_show_about_dialog() (also makes the diff smaller).

The about dialog URI calls are broken on Windows, therefore we needed
a way to override the default URI method. On versions bellow or equal to
GTK 2.24 this is possible with gtk_about_dialog_set_url_hook(),
which on the other hand is deprecated for newer GTK versions.

Commit 90d3c5614a ("Centralising and redefining values as integers")
broke SAC-rate calculations. In particular, it changed "to_ATM()": to
use the centralized SURFACE_PRESSURE helper define, but in the process
it changed a floating point calculation to an integer calculation, and
it threw away all the fractional details. Any user of "to_ATM()"
basically dropped to an accuracy of a single atmosphere.
The good news is that we didn't use to_ATM() for things like depth
calculations, but only for cylinder pressures. As a result, the error
ends up being relatively small, since the pressures involved are big,
and thus the error of rounding to whole atmospheres is usually in the
1% range. The cylinder sizing tends to be off by more than that
anyway. But it was wrong, and not intentional.

The code was written to get the SAC rate correct, but we probably do
want to have the duration and mean depth of the dive always be shown for
the non-surface-time.
So move the code from the sac-rate calculation to the generic dive fixup
part. This makes the dive list and statistics all show the duration as
the under-water duration, which is not necessarily the same as
"difference between beginning and end of dive".

We computed a made-up average depth based on the maximum depth, and used
that. That's questionable even if we didn't have any explicit average
depth to begin with, but it's particularly wrong if we did have an
explicit average depth to use.
Now, admittedly we have no way to actually create fake dives like this
with a particular average depth, so this really doesn't make any
difference in real life. But we should do this right.
Also, make the XML be in the format that subsurface actually saves
things in (mainly things like cylinder sizes having an extra decimal
place, but also ordering of XML elements).

This assumes that you are not breathing your cylinders while at the
surface, which may or may not be correct, but is usually the right
thing. Regardless, we're better off giving a conservative (higher) SAC
rate estimate for a diver that breathes his cylinder at the surface too
than giving an artificially low one because the diver ended up using his
snorkel and we didn't take that into account.
NOTE! This basically calculates a better duration and average depth than
the ones we end up showing in the dive list. Maybe we should actually
show this "no-surface-time" duration and average depth instead of the
ones we do show?
That's a separate question, though.
Added a test-case for the surface case to the sac-test.xml dives.

We even documented that we did SAC in bar*l/min, but the "S" in SAC
stands for "Surface". So we should normalize SAC rate to surface
pressure, not one bar.
It's a tiny 1% difference, and doesn't actually matter in practice, but
it's noticeable when you want to explicitly test for SAC-rate by
creating a test-dive that averages exactly 10m. Suddenly you don't get
the round numbers you expect.
[ Side note: 10m is not _exactly_ one extra atmosphere according to our
calculations, but it's darn close in sea water: the standard salinity
of 1.03 kg/l together with the standard acceleration of 9.81m/s^2
gives an additional pressure of 1.01 bar, which is within a fraction
of a percent of one ATM.
Of course, divers have likely chosen that value exactly for the math
to come out that way, since the true average salinity of seawater is
actually slightly lower ]
So here's a few test-dives, along with the SAC rate fixup to make them
look right.
(There's also a one-liner to dive.c that makes the duration come out
right if the last sample has a non-zero depth, and the previous sample
did not: one of my original test-dives did the "average 10m depth" by
starting at 0 and ending at 20m, and dive.c got a tiny bit confused
about that ;)
[ The rationale for me testing our SAC rate calculations in the first
place was that on snorkkeli.net user "Poltsi" reported that our SAC rate
calculations differ from the ones that Suunto DM4 reports. So I wanted
to verify that we did things right.
Note that Poltsi reported differences larger than the difference of
BAR/ATM, so this is not the cause. I'll continue to look at this. ]

Someone who is better at shell script writing needs to review this.
Here's what it's supposed to do. Create version strings with three or four
values for darwin or win, respectively, that we can use as the versions of
the bundle or installer. The version that Subsurface reports isn't
affected by this. So in a way this is automating something that's mostly
cosmetic.
If we have a 2 digit version number (like 3.0), do the same the old script
did - add just zeroes if we are on a tag, otherwise add the number of
commits since the tag (and a last 0 if on win).
If we have a 3 digit version numner (like 3.0.1), leave it alone on mac
and add either the number of commits since the tag or a zero if we are on
the tag on win.
Now this can create the same version number for two different versions on
darwin: the first commit after 3.0 and the version tagged as 3.0.1 will
both get the same number. That's kinda silly but remember - the non-tagged
versions aren't supposed to be widely distributed (and the third digit in
them should be much larger than anything we'd ever release; we are
already on commit 16 since the last tag and hopefully will never release a
3.0.16 as tagged release). And of course the full version as displayed in
the About box is always able to tell things apart because of the SHA added
at the end if it's a non-tagged version.
So why all this magic? The reason we do this is so that during development
we are able to create Mac and Windows installers and they get reasonable
version numbers, based on the versioning that these vendors suppose. And
without manual intervention.

The problem is that when we reach the gas change depth and compute the
stop time, no gas change event is created yet but time_at_last_depth tries
to determine the gas for the stop from events.

Commit 28aba5a206 ("Flesh out the UDDF xml parsing a bit more")
improved on parsing UDDF files by teaching "percent()" to also handle
pure fractions like UDDF uses. So in a UDDF file, an o2 value of "1.0"
means "100%".
But it turns out that I have a few dives with "1% He", and the "Turn
fractions into percent" logic also turns that into 100%.
So this makes the 'percent()' function a bit smarter. If it actually
finds a percentage-sign after the number, it knows it is already
percent, not a fraction. That disambiguates the two cases: "1.0" is
100%, but "1.0%" (note the explicit percentage sign) is 1%.
So now our native format cannot get confused, because it generally
tries to avoid naked numbers. Good choice.

This uses the example UDDF file from Jan Schubert's Heinrichs Weikamp
DR5 dives, and now parses the dive dates, the cylinder mixes and the gas
switch events correctly (or at least partially).
It's not perfect: the gas mix has an "id" field that we ignore, and
instead we just depend on the cylinders being in order (which they seem
to be). And I have rather limited test-cases, so maybe something else
is messed up too. But for the six example dives I have, this gives
reasonable data.
