willem ferguson 724a07b7e0 Avoid overprinting of cylinder presssure labels for CCR dives
This patch takes the cylinder pressures of CCR dives and prints them
in a non-overlapping way.

Remaining issue: When the dive profile is made taller by dragging the
window or the appropriate slider far down the screen, the labels move
further apart; similarly, when the profle is made flat/shallow by dragging
the window edge or appropriate slider up, the labels get close to each
other and start to overlap.

There are quite a few lines of additional code going into the patch. This
is primarily because separate provisions for when po2 > p(diluent) or vice
versa. In addition, I could not determine the size of the text characters
which would allow much more precise placement of text. This is because the
.scale member of the text is private and not available in the methods
involved in printing the labels. However, the height of the vertical scale
of the cylinder pressure graph can be determined [e.g. vAxis->maximum()].
This helped a lot to get the positioning of the text more or less correct.

While the results of the patch is not perfect, It contributes
significantly to make the profiles of Poseidon dives more readable.
