    <!-- Create a render object.
    If the object will not be re-used, omit the name attribute.
    
    The order of applying transformation methods matters.
    
    Methods include:
    -->

    <append>name</append>
        <!-- Adds the named scene object to the render. -->
    
    <color>r, g, b</color>
        <!-- Sets the beckground color of image.
        Color components of red, green, blue should be numbers of 0 to 1.
        -->
    
    <size>width, height</size>
        <!-- Sets the image size. -->
    
    <save>filename</save>
        <!-- Save the image to a file in PNG, TIF, BMP, JPG
        formats depending on the file extension.
        -->
    
    <show timer="ns" time_deg="deg" key_deg="deg" list="name">name</show>
        <!-- Show the image
        or animate it if the optional attributes of timer, time_deg,
        and key_deg are set; and the named object is a node or plot.
        
        ns - number of mini-second between slides
        deg - change of rotation (degree) between slides
              or when a arrow key is pressed
        
        double click on the left mouse button: start animation
        single click on the right mouse button: stop animation
        double click on the right mouse button: restore to the original state
        
        If the list attribute is set to the name of a node object and
        the named object being animated is also a node oject, each time the timer
        is activated, the contents of the animated node will be replaced by a
        child in the list node sequentially.
