Craig -
I found the documentation confusing too, so once I figured it out
(v3!) I wrote a routine to translate from a bitmap to the vector. If
you blur your eyes a little you can see the cursor shape.
This shows up black; I'm not sure how to set the cursor color.
pro set_cursor

; SET cursor shape and hot spot
