+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):
+    https://github.com/bakkeby/patches/issues/60
