*<action name="WarpCursor" to="output" x="center" y="center" />*
Warp the cursor to a position relative to the active output or window.
*to* [output|window] Specifies the target area of the warp.
Default is "output"
*x* [center|value] Specifies the horizontal warp position within the target area.
"center": Moves the cursor to the horizontal center of the target area.
Positive or negative integers warp the cursor to a position offset by the specified
number of pixels from the left or right edge of the target area respectively.
Default is "center"
*y* [center|value] Equivalent for the vertical warp position within the target area.
Default is "center"
