Summary:
In the header for NSTrackingArea, NSTrackingCursorUpdate is documented as follows: "owner receives cursorUpdate when mouse enters area.  Cursor is set appropriately when mouse exits area"

Unfortunately, it's actually sent to the view associated with the NSTrackingArea. -mouseEntered: and -mouseExited: work correctly (see attached project)

Steps to Reproduce:
Open the project and run.
- Move the cursor over the red rectangle
- Inspect console logs

See attached xcode project.



Expected Results:
-cursorUpdate: should called on the owner object (TrackingAreaOwner)

Actual Results:
-cursorUpdate: called on CursorView instead (see attached project)

Version:
OS X 10.10.3 (14D136)
