title: How to add decoration to OS specific cursor in SWT
body: <p>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. </p>
  
  <p>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?</p>
