+	Set the pointer surface, i.e., the surface that contains the
+	pointer image. This request only takes effect if the pointer
+	focus for this device is one of the requesting client surfaces.
+	If there was a previous surface set with this request it is
+	replaced. If surface is NULL, the pointer image is hidden.
+
+	The parameters hotspot_x and hotspot_y define the position of
+	the pointer surface relative to the pointer location. Its
+	top-left corner is always at (x, y) - (hotspot_x, hotspot_y),
+	where (x, y) are the coordinates of the pointer location.
+
+	On surface.attach requests to the pointer surface, hotspot_x
+	and hotspot_y are decremented by the x and y parameters
+	passed to the request.
+
+	The hotspot can also be updated by passing the current set
+	pointer surface to this request with new values for hotspot_x
+	and/or hotspot_y.
