Basically we could end up in a situation where the plotInfo is no longer
valid, yet the model changes and triggers a redraw before the new data is
passed into the TankBar.
Instead of chasing that race condition it seemed much easier to just copy
the plot_data entries and the gas information in the dive.

In some circumstances Qt will draw a really thick border around
rectangles. This explicitly makes the border of the tank bar thin.

Which actually makes the code much clearer as now the object is at the

Also restructures the code a bit to make it a little more sane and changes
the colors slightly.
With these changes I think we can claim that this

This shows a color-coded bar at the bottom of the graph that corresponds
with the active gas.
Todo:
- text that explicitly states gas on the left edge of the bar
- better vertical positioning of the bar
- ability to turn this on and off
