; Changed on Feb 4, 1999 by Piet van Oostrum <piet@cs.uu.nl>
; For use with GIMP 1.1.
; All calls to gimp-text-* have been converted to use the *-fontname form.
; The corresponding parameters have been replaced by an SF-FONT parameter.

;;; Comment:
;;;  This is the first font decoration of Imigre-26 (i26)
;;; Code:
