Cant zoom when distance hit 0.00 and minimumDistance is set to 0 #15

The following line is used to calculate the distance on zoom: 

private void mouseZoom(final double delta) {
    safeSetDistance(distance + delta * Math.log1p(distance));
}

So, when the distance is 0 and the minimumDistance is also 0 or lower you cant zoom out anymore. Also minimumDistance lower then 0 will cause distance to be NaN in some cases.
