Warping the pointer could be quite difficult to implement.
We would have to make sure that we're supposed to be in control of the
pointer on the client side by the time we get the message, and I could
see some users would never want to have xpra control the cursor.
We would also need to figure out when those warped pointer events should
be honoured: distinguishing between the warp pointer events that we
generate ourselves and the ones that other applications can generate
(all asynchronously..)
It may be possible, but this isn't high on the priority list at the
moment. If you can create a ticket for it, at least it won't be forgotten.
