Subject: [PATCH] Now warping mouse to center of screen when leaving client
 screens. Some users requested this.  Also, the hider window is mapped before
 warping the mouse so the active window shouldn't change if the focus policy
 is point-to-focus.  Showing the window first can also reduce the likelihood
 of seeing the cursor briefly in its hidden position.
