[Openmcl-devel] ns:ns-tracking-area not present in 32bit CCL

[Arthur W Cater]

Use #/addTrackingRect:owner:userData:assumeInside: with
- the view
- its #/bounds
- a ns-object as target
- ccl::+null-ptr+
- #$NO

Then
(objc:define-objc-method ((:void :mouse-entered (:id event)) <theTargetClassYouUsed>) ...)

likewise :mouse-exited and :mouse-move
