Reinstating SURFACE_THRESHOLD test in pressure_time function

Browse source 
The small straight parts at the end of tank pressure lines are more of a
aesthetic issue, not causing real harm so it is no reason to remove the
SURFACE_THRESHOLD test from pressure_time function only because of this.

Also improved interpolate data debuging, rearranged
get_pr_interpolate_data and removed an unused variable from
get_pr_interpolate_data. No real change here, just trying to make the code
clearer.
