As far as I can tell there is no such thing as QueryPoint.

As far as I can tell there is no such thing as XQueryCursor either.
The only thing I can think of that makes any sense is XQueryPointer,
and I haven't seen anything wrong with that.

"The hotspot comes from the information stored in the cursor font.",
according to the Xlib document.  As far as I can tell there is no way
to change the hot-spot of a cursor once it's created, so the hot-spot
should be correct.

If you can reduce it to a small sample program, I'd be glad to try it
here, and see if I can see anything wrong....
