;  bitmap fonts on most installations. If you want better quality versions
;  you need to grab the urw font package form www.gimp.org/fonts.html
;  and install as indicated. This will replace the some current bitmap fonts
;  with higher quality vector fonts. This is how the actual www.gimp.org

; 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; The corresponding parameters have been replaced by an SF-FONT parameter.
