Tweak cylinder equipment tooltips 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 adaeb506b7a1 ("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.

Tweak the "display_unused_tanks" preferences logic This is really unrelated to my recent "multiple gas pressures" work, but the test case from Gaetan Bisson showed that the logic for which cylinders to show in the equipment tab was less than optimal. We basically used to show only cylinders that were actively used, unless you had the "display_unused_tanks" preference option set. That comes from some dive computers reporting a *lot* of cylinders that the diver really doesn't even have with him on the dive. And showing those extra dummy cylinders gets pretty annoying after a time, which is why we default to not showing unused tanks. However, in Gaetan's case, he had a total of four cylinders on the dive: the O2 and diluent bottle for the rebreather dive, and then bailout bottles (both air and deco). And while the bailout bottles weren't actually used, Gaetan had actually filled in all the pressure details etc for them, and so you'd really expect them to show up. These were *not* just some extraneous default cylinder filled in by an over-eager dive computer. But because the bailout wasn't used, the manual pressures at the end were the same as at the beginning, and the "unused cylinder" logic triggered anyway. So tweak the logic a bit, and say that you show cylinder equipment not only if it has been used on the dive, but also if it has any pressure information for it. So the o nly cylinders we don't show are the ones that really have no interesting information at all, except for possibly the cylinder tank type itself (which is exactly what the over-eager dive computer case might fill in, usually in the form of a default cylinder type).

So tweak the logic a bit, and say that you show cylinder equipment not only if it has been used on the dive, but also if it has any pressure information for it. So the o nly cylinders we don't show are the ones that really have no interesting information at all, except for possibly the cylinder tank type itself (which is exactly what the over-eager dive computer case might fill in, usually in the form of a default cylinder type).

Tweak the "display_unused_tanks" preferences logic This is really unrelated to my recent "multiple gas pressures" work, but the test case from Gaetan Bisson showed that the logic for which cylinders to show in the equipment tab was less than optimal. We basically used to show only cylinders that were actively used, unless you had the "display_unused_tanks" preference option set. That comes from some dive computers reporting a *lot* of cylinders that the diver really doesn't even have with him on the dive. And showing those extra dummy cylinders gets pretty annoying after a time, which is why we default to not showing unused tanks. However, in Gaetan's case, he had a total of four cylinders on the dive: the O2 and diluent bottle for the rebreather dive, and then bailout bottles (both air and deco). And while the bailout bottles weren't actually used, Gaetan had actually filled in all the pressure details etc for them, and so you'd really expect them to show up. These were *not* just some extraneous default cylinder filled in by an over-eager dive computer. But because the bailout wasn't used, the manual pressures at the end were the same as at the beginning, and the "unused cylinder" logic triggered anyway. So tweak the logic a bit, and say that you show cylinder equipment not only if it has been used on the dive, but also if it has any pressure information for it. So the o nly cylinders we don't show are the ones that really have no interesting information at all, except for possibly the cylinder tank type itself (which is exactly what the over-eager dive computer case might fill in, usually in the form of a default cylinder type).
