Dive planner oddities

[Rick Walsh]

Hi Sergey,

Thanks for testing the planner.  The more people that try it and the more
feedback the better.

this is what „recreational mode“ is about: The second handle is the last
manually entered waypoint and in recreational mode the planner stays at
that depth for the maximum time that does not get you in conflict with gas
usage and deco obligations.

Maybe we should also add a tooltip on recreational mode saying something
like, "maximize bottom time without deco".

The cylinder pressure graph should start to flatten when starting ascent.
Assuming a constant SAC, gas consumption varies with depth.  Is that what
you're referring to?

Cheers,
