This splits the dive time, depth, pressure and temperature maxima and
minima setup from the per-dive-computer "create_plot_info()" function
into one setup function that walks _all_ the dive computers, so that we
have a global maxima and minima.
That way the graph scaling we set up will now fit the data from all dive
computers rather than just the particular one we are plotting. So if
you switch back-and-forth between computers, the scale (which is defined
by the extremes) remains the same.

This commit changes the code that was recently introduced to deal with
deco ceilings. Instead of handling these through events we now store the
ceiling (which in reality is the deepest deco stop with all known dive
computers) and the stop time at that ceiling in the samples.
This also adds support for NDL (non stop dive limit) which both dive
computers that appear to give us ceiling / deco information appear to
give us as well (when the diver isn't in deco).
If the mouse hovers over the profile we now add support for displaying the
NDL, the current deco obligation and (if we are able to tell from the
data) whether we are at a safety stop.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
I was a little too eager to add the deco feature to Subsurface. Jef and I
went back and forth a few more times and the definition of those events
changed. I guess I shouldn't have commited that code until the
corresponding libdivecomputer code had been pushed.
This commit now brings us in sync with the current master of
libdivecomputer (but should compile with 0.2 as well - only deco events
won't work then).
One issue that I see is that deco / ndl aren't really a good fit for the
event model. I actually disabled the drawing of the little yellow
triangles for ndl events as for example on the Uemis those events are
created whenever the remaining non stop time changes - and that can be
every few seconds.
The correct solution may be to treat this as a function of the samples,
but for now this works and is tested with both OSTC and Uemis SDA.

This actually triggers for one of our insane test dives (test15): it has
no samples, so we created a fake dive computer entry with the a fake
profile in it, but we didn't copy the events over.
Having a dive with no samples, yet having events from the dive computer,
sounds pretty bogus. But that test-case did show that when that bogus
situation happens, we had two independent buglets: (a) we didn't insert
the entries in the fake dive computer entry we used and (b) we would
then mix up the events of the fake dive computer entry with the first
dive computer of a dive.
Fix this, just to make test15 happy again. And eventually, when we
actually plot the information for multiple dive computers, fixing case
(b) would become necessary even for real dives.

Commit 6c52e8a2e5 ("Add plotting of the deco ceiling") for some

some plot events not having a time at all. Which causes various really

to the difference in times between events being nonsensical.

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 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

necessary information to plot this. I have sent patches for the OSTC to

We always want to print absolute maxima and minima - but not when multiple

So far this is done unconditionally. This already starts some of the

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.

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.
