The memory referenced by this vertex view's pointer may be owned by another object, such that the memory is
automatically freed when the other object becomes phantom reachable or is garbage collected.
The memory referenced by this vertex view's pointer may be owned by another object, such that the memory is
automatically freed when the other object becomes phantom reachable or is garbage collected. Use this method to
ensure this vertex view retains a strong reference to the memory owner so this vertex view's pointer remains
valid even when no other references to the memory owner are retained.
