Prervent tiny temperature changes from being exaggerated in the plot.
Also, shift pressure plot around a bit (if necessary) to prevent it from
ending in the same space as the temperature plato on the profile graph.

The code in commit f99e1b476b18 "Trim the dive to exclude surface time at
beginning and end" failed rather badly if a dive has no samples at all -
which is true for many of our test dives.
This makes sure that we don't exclude data points if we never set up start
and end times.

Commit 6c52e8a2e516 ("Add plotting of the deco ceiling") for some
totally unexplained reason deleted one "else" statement, resulting in
some plot events not having a time at all. Which causes various really
odd issues if you hit that situation, including divide-by-zero etc due
to the difference in times between events being nonsensical.
It's just some odd mistake that was entirely unrelated to the other
changes in that commit.
Add the missing line back in.

This shows the values for all the graphs that are shown (depth,
temperature, tank pressure, pO2, pN2m pHe), but also correctly doesn't
display them when they are turned off or no data is available (prior to
this commit, tank pressure was always shown, even if no pressure samples
were available for the dive).

When we calculate the interval for the tick-marks for the dive, we need
to limit 'i' to be within the size of the array. The code does that
with a "i < 8" check, but the fact is, we must never increment past the
last entry, which is 7 (the size of the array is 8, but the last valid
index is 7).
This only happens for unrealistically long dives. Which you can trigger
either by inputting insane values for a manually created dive, or by
merging two dives that are consecutive, but not close to each other
time-wise (eg on different days ;)

This extends on our current tooltip logic (which shows events when you
mouse over them) to show tooltips for the whole profile area.
If you mouse over an event, that is still shown in the tooltip, but
even in the absense of events, the tooltip will be active, and mousing
over the profile area will show the time, depth and pressure.
This can certainly be improved upon further, but even in this form it is
useful.

We don't change any of the samples, we just don't plot (or consider for
dive time / mean calculations) the samples at the beginning or end of the
dive that are less than a certain threshold under water. Right now that's
an arbitrary 75cm which seems to Do The Right Thing(tm) for the dives I
tried this with - but I'm happy to look at other values if this causes
problems for people with dive computers I do not have access to.

We now throw away redundant events, just as we throw away other redundant
data coming from the dive computer. Events are considered redundant if
they are less than 61 seconds apart and identical.
This also improves the display of the remaining events in the profile as
we now show the value of the event, if it is present (for example for a
deco event we show the duration of the deepest stop).
Finally, for events that define a range (so they set the beginning flag
and assume and end flag some time later) we no loger show the triangle but
assume that some other code handles visualizing them (as happens for the
ceiling events).

Based on suggestions from Linus (and a few iterations) we now simply have
the surface (i.e., background color / pattern) come down to where the
ceiling is. And we only do the angry red shading when the diver violates
the ceiling.
I think this looks much better.

Plot a red-shaded area on top of the depth profile to indicate the deco
ceiling (i.e., the area into which it isn't save to ascend at this point
of the dive.
So far this is of very limited use as libdivecomputer doesn't give us the
necessary information to plot this. I have sent patches for the OSTC to
Jef, hoping that he will include them in an update. I don't know how many
other dive computers will make this data available - I still need to add
this to our native Uemis support.
This commit also fixes two cut and paste errors in the previous commit
6540be9bd924 "Process ceiling events and store ceiling data in plot_info".

The existing implementation failed on dive computers that did gas changes
based on events (instead of tracking them in the sample data like the
Uemis Zurich does that I tested the code with).
This commit moves the calculations slightly later in create_plot_info()
after the gas change events are processed and the plot_info data has been
fixed up. Now this works with the data from Linus' Suunto as well.

The pN2 print shouldn't have been committed, but I don't want to try and
rewrite all the commit history. Oh well.
The pressure scale I am ambivalent about. It seems that it should be
useful - but that would require guide lines that coincide with the values
which would really throw off the visual for me. So I added the code, but

We always want to print absolute maxima and minima - but not when multiple
consecutive data points all have the same value (this happens, for
example, when printing a pHe plot on non-helium dives - or when the dive
profile includes a brief surface intervall which causes all the partial
pressures to be at their minimum).

Whatever I pick here, there will be dives where the different graphs end
up interfering with each other. I don't think there isn't an easy, generic
solution for this (but I can envision awesome non-easy solutions - they
just don't seem to be worth the effort).
But for most dives that I played with this seems to work pretty well.

Not sure this is the best naming scheme (General Settings / Tec Settings)
but it's a start.
The idea is to have the settings that a recreational diver might care
about on the first page, and all the other stuff on the second one. Let's
see how this works out long term. For now I moved OTU over and added
toggles for the different partial pressure graphs (only the pO2 one is
implemented so far).

So far this is done unconditionally. This already starts some of the
infrastructure for other gases, but so far only O2 is handled.
We also need a pressure scale on the right to make this useful - or we
need to do peek / trough pressure prints like we do for temperature and
depth.
Finally, I think I want to move the plot further down, maybe make the
whole plot area taller if we are plotting partial gas pressures as well.

Here is what Linus reported:
I think you have made a mistake in trying to translate some of
libdivecomputer.c
Translating some of those things based on locale is *wrong*, because
they are saved in the XML file.
That covers at least the warnings: they'll get translated when you
import them, and then saved to the XML file as that translation, but
now if you start subsurface in another locale, they will not get
translated back.
So translating XML file contents is fundamentally buggy. It just
shouldn't be done.
So all the "translations" for the event handling are buggy, and
generate crap. Please don't do that. Leave them as English.
And of course he is absolutely right. However, instead of not translating
them at all, this commit fixes things a better way - we now mark the
strings for translation but store the original English strings everywhere
(in the in-memory data structure as well as in the XML file). Only when we
actually display something on the screen (in a tooltip or in the filter
dialog) do we actually translate the strings into the native language.
This should address both Linus' issue and the desire to have localized
event texts.

This is just the first step - convert the string literals, try to catch
all the places where this isn't possible and the program needs to convert
string constants at runtime (those are the N_ macros).
Add a very rough first German localization so I can at least test what I
have done. Seriously, I have never used a localized OS, so I am certain
that I have many of the 'standard' translations wrong. Someone please take
over :-)
Major issues with this:
- right now it hardcodes the search path for the message catalog to be
./locale - that's of course bogus, but it works well while doing initial
testing. Once the tooling support is there we just should use the OS
default.
- even though de_DE defaults to ISO-8859-15 (or ISO-8859-1 - the internets
can't seem to agree) I went with UTF-8 as that is what Gtk appears to
want to use internally. ISO-8859-15 encoded .mo files create funny
looking artefacts instead of Umlaute.
- no support at all in the Makefile - I was hoping someone with more
experience in how to best set this up would contribute a good set of
Makefile rules - likely this will help fix the first issue in that it
will also install the .mo file(s) in the correct place(s)
For now simply run
msgfmt -c -o subsurface.mo deutsch.po
to create the subsurface.mo file and then move it to
./locale/de_DE.UTF-8/LC_MESSAGES/subsurface.mo
If you make changes to the sources and need to add new strings to be
translated, this is what seems to work (again, should be tooled through
the Makefile):
xgettext -o subsurface-new.pot -s -k_ -kN_ --add-comments="++GETTEXT" *.c
msgmerge -s -U po/deutsch.po subsurface-new.pot
If you do this PLEASE do one commit that just has the new msgid as
changes in line numbers create a TON of diff-noise. Do changes to
translations in a SEPARATE commit.
- no testing at all on Windows or Mac
It builds on Windows :-)

Tests have shown that the most multi-platform way to do printing with GTK is
to use GTK_UNIT_INCH (or GTK_UNIT_MM) with GtkPrintOperation. Tested on
Linux, OSX, Windows.
However this requires the appropriate scaling for Pango and Cairo to be done,
with separate plotting logic for printing and drawing on the screen. To achieve
that, profile.c:plot() now accepts a scaling parameter from type
"scale_mode_t" defined in "display.h".
Also due to new scale, small decimal numbers (such as 6.12345) cannot be well
stored in "cairo_rectangle_int_t" therefore it is replaced with
"cairo_rectangle_t", which uses doubles to provide Cairo with a drawing
area.

The previous commit was a patch from Lubomir, which also had some
whitespace fixes (to go with some new whitespace bugs to replace them)
in it.
I removed the whitespace changes from that patch (don't mix whitespace
fixes with other fixes, unless they are on the same lines!) but decided
to look for other whitespace issues, and this is the result.
I left the non-C files alone, some of the spec and script files also
have whitespace at the end of lines etc.

This completely changes how we keep track of selected dives: instead of
having an array listing the selection ("selectiontracker") or trusting
the gtk selection information, just save the information about whether a
dive is selected in the dive itself.
That makes it trivial to keep track of the state of selection across
group collapse/expand events, or when changing the tree view model. It
also ends up simplifying the code and logic in other ways.
HOWEVER, it does currently (re-)introduce an annoying oddity with gtk:
if you collapse a dive trip that has individual selections, gtk will
forget those selections ("out of sight, out of mind"), and when you do
*new* selections, the old hidden ones remain.
So there's some games required to make gtk do sane things. We may need
to either explicitly drop selections when collapsing trips, or make sure
the group entry gets selected when collapsing a group that has
selections in it. Or something.
There may be other issues introduced by this too.

This calculates a mean depth for the dive with a fixed ascent/descent
rate and an assumption that all of the bottom time is at the maximum
depth. It's not much, but it allows some derived values such as SAC to
make more sense.
The depth profile for such dives is now also generated with the same
assumptions instead of putting the samples at fixed percentages of the
dive duration.
