<AWT Dev> [8] Review request for 8007155 [macosx] Disabled panel takes mouse input in JLayeredPane

[Alexander Scherbatiy]

Hello,

Could you review the fix:
   bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8007155
   webrev: http://cr.openjdk.java.net/~alexsch/8007155/webrev.00


   The findComponent method in the LWCursorManager class searches from a 
component under the mouse
   to the parent components and does not take in the account another 
components under mouse that intersects the disabled one.

   The fix adds the necessary findComponentAt method to the container 
accessor and uses it in the *CursorManager classes.
   The same issues is fixed for the XGlobalCursorManager.
   Unnecessary call from native method is removed for the 
WGlobalCursorManager.

   Manual test is added because there is no way to know the actual mouse 
cursor type.

Thanks,
Alexandr.
