Maps a position in some buffer in the graph to a position in a matching buffer that is lower in the graph and to which an insertion would be routed. Source buffers are considered to be lower than the projection buffers that consume them.

- position
- SnapshotPoint
the position in a buffer in the graph.
- trackingMode
- PointTrackingMode
How position is tracked to the current snapshot if necessary.
- match
- Predicate<ITextSnapshot>
The predicate that identifies the target buffer.
Returns
A point in a snapshot of some source buffer, or null if position is not in this graph or does not
map down to any buffer selected by match.
Exceptions
position.Snapshot or match is null.
trackingMode is not a valid PointTrackingMode.
