 * DESCRIPTION:
 *   Write an RGB image to a file.  Image routines donated by John Stone,
 *   derived from Tachyon source code.  For now these image file writing
 *   routines are statically linked into VMD and are not even in an extensible
 *   list structure.  Long-term the renderer interface should abstract from
 *   most of the details, and use a plugin interface for extensibility.
 *   For the short-term, this gets the job done.
