- A Depth object is null (has never been initialized) if all depths are null.

add
public void add(Label lbl)
getDelta
public int getDelta(int geomIndex)
normalize
public void normalize()
- Normalize the depths for each geometry, if they are non-null.
A normalized depth
has depth values in the set { 0, 1 }.
Normalizing the depths
involves reducing the depths by the same amount so that at least
one of them is 0. If the remaining value is > 0, it is set to 1.
