4 Subject: [PATCH] Warp patch
5
6 Warps the mouse cursor to the center of the currently focused
7 window or screen when the mouse cursor is
8 (a) on a different screen, or
9 (b) on top of a different window.
10
11 This version properly handles warping to windows that have not been
12 mapped yet (before it resulted in a change of the stack order).
13 See the discussion in (thanks goes to Bakkeby):
