Handle z_at_xy_zero being very large.

When z_at_xy_zero starts off very large, subtracting z_delta from it might still leave it larger than kInfiniteCoordinate, so we can't assume that it is smaller. Just forcing it to be smaller should be good enough given how much of an edge case this is. (We won't get sensible results anyway, since the inaccuracy of floating point will have made them wildly inaccurate already.)
