How to add decoration to OS specific cursor in SWT

问题

I'd like to change the cursor on an SWT Composite to add a small image to the standard OS arrow cursor, in the bottom right corner for instance.

I imagine it will mean somehow getting hold of the Image and X,Y hotspot of the cursor but I can't figure how do do that. Any thoughts?

EDIT: Following the comment this has spawned this question.
