    wacom: Fix first animation of calibration UI
    
    The "target" was seen moving from 0,0 to the first calibration
    point, so 1) avoid target relayouts when the window is still
    being positioned and 2) start the "target" actor as hidden so
    it isn't seen moving from anywhere when first shown.
