elevate_land() computes the sequence of elevations 97, 97 - delta,
... in fixed point with a scaling factor of 100. Switch to
floating-point, because it's simpler. Elevations (and thus resources)
change slightly due to reduced rounding errors.
Note that we map elevations less than 1 to 1 both before and after the
patch. Odd. Turns out this mitigates a bug: mountain placement can
place fewer mountains than it should, and when that happens,
elevations go below 1 here. The next commit will fix this.
