Subtraction(SnapshotPoint, SnapshotPoint)
Computes the offset between two SnapshotPoint objects.

- start
- SnapshotPoint
The starting point.
- other
- SnapshotPoint
The point from which to compute the offset.
Returns
The offset between the two points, equivalent to start.Position - other.Position.
Exceptions
The two points do not belong to the same snapshot.
Remarks
The following should always be true: start == other + (start - other).

- point
- SnapshotPoint
The point from which to calculate the new position.
- offset
- Int32
The offset of the new point.
Returns
An integer representing the position.
Exceptions
The new point is less than zero or greater than Snapshot.Length.
