 * NAME:        IFD_RenderDefinition.h ( IFD Library, C++)
 *
 * COMMENTS:    The capabilities of renderers are dynamic and may change from
 *              release to release.  The default expected behaviour is that the
 *              renderer doesn't have the capability.
 *              
 *              The current list of capabilities are:
 *                      script          - The output can generate a script
 *                      command         - The output can be piped to a command
 *                      background      - Can support background rendering
 *                      archive         - Has a method of generating archives
 *                      hasrop          - Has a specific ROP associated with it
 *                      image           - Output driver generates a picture
 *                      fields          - Can render video fields
