        screen only after a XSpriteCanvas::updateScreen() call at the
        associated sprite canvas. This canvas is not equivalent to the
        host canvas of the sprite. At the very least, all output
        happens relative to the sprite's upper left corner, i.e. the
        origin of the sprite's canvas device coordinate system will
        move with the sprite across the screen.
