; GIMP - The GNU Image Manipulation Program
; Copyright (C) 1995 Spencer Kimball and Peter Mattis
;
; Bump-mapped title script --- create a bump-mapped title image for web pages

; federico@nuclecu.unam.mx
; ************************************************************************
; Changed on Feb 4, 1999 by Piet van Oostrum <piet@cs.uu.nl>
; For use with GIMP 1.1.
;
; The corresponding parameters have been replaced by an SF-FONT parameter.
; The call to gimp-context-set-background has been given a real layer
; (although it is not used) otherwise gimp 1.1 crashed.
