Reviewer: swingler

Rationale for inclusion in 7u4: Since 1.3 release, there is an approach adopted for cursors created from non-existent image to make them transparent. It is an additional well-known if not exactly documented feature (see discussion in 4212593). This behavior was implemented in Apple jdk6.

Thanks,
Leonid.
