The ratio between SAC and oxygen metabolism rate can be assumed constant
but not the metabolism rate. So we better base our calculation on the ratio
that uses the SAC from the preferences as that pairs well with the O2
consumption from the preferences.
Hence we ran remove the sac parameter from fill_pressures().

This patch is bigger than necessary because I also renamed the

If we have no gas changes (except for a possible explicit first gas),

correct per cylinder depth and duration for oxygen and diluent and
therefore create more reasonable gas consumption data for CCR dives.

Calculations for passive semi-closed rebreathers are pretty much like OC
except the pO2 is lower bey a certain (SAC dependent) factor. This patch
introduces the corresponding calculations in case dctype == PSCR which is
so far never set and there is currently no UI for these calculations. As
pO2 is SAC dependent it takes a certain attempt at getting it and drops to
defaults from the prefs otherwise.
As there is no UI at this point and I also don't have any dives, this has
not received much testing, yet, but it compiles. At least.

Currently the gas pressures stored in structures of pressure are
calculated using the gasmix composition of the currently selected
cylinder. But with CCR dives the default cylinder is the oxygen
cylinder (here, index 0). However, the gas pressures need to
be calculated using gasmix data from cylinder 1 (the diluent
cylinder). This patch allows setting the appropriate cylinder
for calculating the values in the structures of pressure. It
also allows for correctly calculating gas pressures for any
open circuit cylinders (e.g. bailout) that a CCR diver may
use. This is performed as follows:
1) In dive.h create an enum variable {oxygen, diluent, bailout}
2) Within the definition of cylinder_t, add a member: cylinder_use_type
This stores an enum variable, one of the above.
3) In file.c where the Poseidon CSV data are read in, assign
the appropriate enum values to each of the cylinders.
4) Within the definition of structure dive, add two members:
int oxygen_cylinder_index
int diluent_cylinder_index
This will keep the indices of the two main CCR cylinders.
5) In dive.c create a function get_cylinder_use(). This scans the
cylinders for that dive, looking for a cylinder that has a
particular cylinder_use_type and returns that cylinder index.
6) In dive.c create a function fixup_cylinder_use() that stores the
indices of the oxygen and diluent cylinders in the variables
dive->oxygen_cylinder_index and dive->diluent_cylinder_index,
making use of the function in 4) above.
7) In profile.c, modify function calculate_gas_information_new()
to use the above functions for CCR dives to find the oxygen and
diluent cylinders and to calculate partail gas pressures based
on the diluent cylinder gas mix.
This results in the correct calculation of gas partial pressures
in the case of CCR dives, displaying the correct partial pressure
graphs in the dive profile widget.

This isn't Cobalt specific, this is specific to dive computers that
indicate the first tank that's in use with a gaschange event that
coincides with the first sample.
We need to make sure that we suppress showing that gas change event
(regardless which cylinder it goes to) and instead set the correct
cylinder index from the very start of the dive.
This works with the test data I have and doesn't seem to break thing with
any of the files that I tried... but I'm worried that this is not the
right way to do things.

respect to ceilings in OC dives and dive plans. Dive ceilings are now
calculated correctly again.
The following were performed:
1) remove the oxygen sensor and setpoint fields from the gas_pressures
structure.
2) Re-insert setpoint and oxygen sensor fields in the plot_data structure.
3) Remove the algorithm that reads the o2 sensor data and calculates the
pressures.po2 value from function fill_pressures() in dive.c and save
it as a separate function calc_ccr_po2() in profile.c.
4) Activate calc_ccr_po2 from function fill_pressures() in profile.c.
5) Move the relative position of the call to fill_pressures() within the
function create_polt_info_new() in profile.c.

This patch adds code to the function fillpressures() in dive.c to
allow calculating o2 pressures, based on the data from the po2
sensors in the system. The following changes were made:
1) add code to perform po2 calculations for CCR with 1, 2 or 3
oxygen sesnors.
2) Add four fields to the gas_pressures structure in dive.h. This
allows communication of data between the function that calls
get_pressures() and the return of partail pressure values to the
calling function.
3) Delete the fields for setpoint and gas partial pressures from
the structure plot_info. All partial pressures (from instruments
as well as calculated) now reside in the pressures structure
that forms part of plot_info.
4) Perform changes in several parts of profile.c to make use of the
pressures structure in plot_info.

With this information, when we re-plan a dive we can bring the user right
back to the point where they ended - they have the waypoints in the dive
pointes table and handles are shown on the right points in the profile -
and the rest of the dive is once again calculated by the planning
algorithm.
For now this state is lost when saving the dive file as we don't add this
flag in the sample to our saved files. So if we don't find any samples
marked as manually added we add ALL of the samples as way points on the
diveplan and the user has to manually remove the ones that were

So far, the fields for the two SAC rates did not show a unit and were implictly l/min.
Now they respect the settings for volume units. This was harder than I thought for two reasons:
1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point
the field prefix and what is entered is actually hundreth of cuft per minute.
2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min
internally) which would then become 19l/min when switching back.
While being at it, I gave the gradient factors '%'-signs as units.
