When painting the tankbar the function triggers on change in cylinder index,
as a result the new gascolour are changed at the next sample time point.
On a divecomputer with a reasonable fast sample rate the 2-3s offset are hardly
noticable, especially on a longer dive.
For divecomputers with slow sample rate the 10-30s offset are clearly visible.
This is fixed by start painting the new gascolour at the time point of the switch event rather than the time point of the next sample.

In commit 70e2404492 ("Stop accessing the internals of
dc_descriptor_t") the structure definition of the libdivecomputer
descriptor was removed from Subsurface and replaced with accessor
functions. This adapts the Smart Trakl import tool to use the same
accessor functions, which allows it to compile again in current master.

We had hardcoded the exact translation of the event numbers. They
haven't changed (although we did have what appears to be a spurious
entry for "non stop time" at the end that libdivecomputer doesn't have
an enum for).
Instead, use an explicit array index initializer array, so that it's
obvious that the two match up (and if the sample event numbers ever
change, we should cope with it gracefully).

New libdivecomputer versions use DC_SAMPLE_GASMIX to indicate a gas
change (which contains the cylinder index we're changing to) rather than
SAMPLE_EVENT_GASCHANGE*.
Unlike the old GASCHANGE model, and despite the name, DC_SAMPLE_GASMIX
does not actually say what the mix is, it only specifies a cylinder
index. We had already extended SAMPLE_EVENT_GASCHANGE2 to have the
cylinder index in the otherwise unused "flags" field, so this is not all
that different from what we used to do.
And subsurface internally already had the logic that "if we know what
the cylinder index is, take the gas mix from the cylinder data", so
we've already been able to transparently use _either_ the actual gas mix
or the cylinder index to show the event.
But we do want to make it an event rather than some sample data, because
we want to show it as such in the profile. But because we are happy
with just the cylinder index, we'll just translate the DC_SAMPLE_GASMIX
thing to the SAMPLE_EVENT_GASCHANGE2 event, and nothing really changes
for subsurface.
libdivecomputer has made other changes, like indicating the initial
cylinder index with an early DC_SAMPLE_GASMIX report, but we've seen
that before too (in the form of early SAMPLE_EVENT_GASCHANGE events), so
that doesn't really end up changing anything for us either.
HOWEVER, one thing that is worth noticing: do *not* apply this patch and
then use an old libdivecomputer library that sends both the
DC_SAMPLE_GASMIX samples _and_ the deprecated SAMPLE_EVENT_GASCHANGE
events. It will all *work*, but since subsurface will take either,
you'll then get duplicate gas mix events.
It's not like that is in any way fatal, but it might be a bit confusing.

This reverts commit adaeb506b7.
commit a8e8d56ec0 ("Tweak cylinder equipment tooltips") does a much
better job allowing the user to know the true volume of the cylinder
(given the gas entered) and clutters the UI a lot less.
While playing around with the current subsurface, I realized that while we
give the gas volume and Z factor for the beginning/end pressures in the
newly added tooltips, there is no way to actually see that same
information for the working pressure.
So if you have filled in cylinder type information, but don't have any
actual gas usage information, there will be no cylinder tooltips at all.
But you might still want to know what the actual volume for a particular
cylinder is, and what the Z value for that working pressure is.
So this tweaks the tool-tips a bit.
When mousing over the pressure fields (ie "working pressure", "start" and
"end"), it now always gives the cylinder gas volume and Z factor for that
pressure, so for example on an AL72 that has a working pressure of 3000
psi and that contains air the tooltip will say:
69 cuft, Z=1.040
when you mouse over the working pressure field (that's obviously with
imperial units, in metric you'll see liters of gas).
When mousing over the type/size field, it gives the used gas amounts, ie
something like this:
37 cuft (82 cuft -> 45 cuft)
but if the cylinder doesn't have starting/ending pressures (and thus no
used gas information), this patch will make subsurface show the working
pressure data instead, so that you at least get something.
This all seems more useful than what my first version gave.
NOTE! This makes commit adaeb506b7 ("Show both the nominal and "real"
size for an imperial cylinder") kind of pointless. You now see the real
size in the tooltip when you mouse over the size, and now it actually
works both for imperial and metric people, so the tooltip is in many ways
the better model.

This adds tooltips for the equipment tab for each cylinder, showing the
amount of gas used.
When you mouse over the size and working pressure fields, the tooltip will
show the amount of gas used (along with start and end gas volumes). And
when you mouse over the start and end pressures, it will show the start
and end gas volumes, and the Z factor used.
I started doing this because of the gas volume questions in the last day
or two (and a few from a few weeks ago). When even Robert Helling starts
wondering about the effects of compressibility on the SAC calculation, our
numbers are clearly too opaque.
With these tooltips, at least you can see what went into the used gas
calculations, instead of having to add debugging options to print out Z
factors.
[ This patch also adds a "rint()" to get the rounding right in the
gas_volume() function. Although rounding to the nearst milliliter
really doesn't matter, it's the right thing to do after doing FP
calculations ;^]
