Rémi Verschelde 94721f5ab8 Revert "Renamed plane's d to distance"
This reverts commit ec7b481170.

This was wrong, `d` is not a distance but the `d` constant in the
parametric equation `ax + by + cz = d` describing the plane.

Plane in hessian form.

<description>
Plane represents a normalized plane equation. Basically, "normal" is the normal of the plane (a,b,c normalized), and "d" is the distance from the origin to the plane (in the direction of "normal"). "Over" or "Above" the plane is considered the side of the plane towards where the normal is pointing.
