In the Aqua build of Tk, warping the pointer doesn't work in either 8.5.8 or 8.6b1. SImple script to reproduce:

package require Tk
bind . <1> { puts "Yes"; event generate . <Motion> -warp 1 -x 5 -y 5 }

in X11/MacOS, this warps the pointer as expected when clicking anywhere in the main window. This functionality is needed e.g. for a 3D game, where the pointer is hidden and only the motion is tracked.

    Fixed for HEAD. It's a bit of an intrusive fix though (needed a change to the global TkDisplay structure) so I'm not going to backport. (DAS: if you want to backport, note that you want CGPostMouseEvent and not CGWarpMouseCursorPosition; odd things happen if you use the wrong one.)
