   #                      http://bugs.lon-capa.org/show_bug.cgi?id=5631

   #   resource   - The resource to include.  This is passed directly, without

   #   form       - The form hash parameters that guide the interpretation of the resource
   #                
   #   retries    - Number of retries allowed before giving up completely.

   #   On success, returns the rendered resource identified by the resource parameter.
   # Side Effects:
   #   The following global variables can be set:
   #    ssi_error                - If an unrecoverable error occurred this becomes true.
   #                               It is up to the caller to initialize this to false
   #                               if desired.

   #                               of the resource that could not be rendered by the ssi
   #                               call.
