|Subject: [PATCH] Warp patch
|
|Warps the mouse cursor to the center of the currently focused
|window or screen when the mouse cursor is
|  (a) on a different screen, or
|  (b) on top of a different window.
|
|This version properly handles warping to windows that have not been
|mapped yet (before it resulted in a change of the stack order).
|See the discussion in (thanks goes to Bakkeby):
