; The GIMP -- an image manipulation program
; Copyright (C) 1995 Spencer Kimball and Peter Mattis
;
; Supposed to look vaguely like roughly carved wood. Chipped away if you will.
;
; Options: Text String - the string to make the logo from
; Font - which font to use
; Font Size - how big
; Chip Amount - how rought he chipping is (how spread the bump map is)
; Blur Amount - the bump layer is blurred slighty by this amount
; Invert - whether or not to invert the bumpmap (gives a carved in feel)
; Drop Shadow - whether or not to draw a drop shadow
; Keep bump layer? - whether to keep the layer used as the bump map
; fill bg with pattern? - whether to fill the background with the pattern or leave it white
; Keep Backgroun - whether or not to remove the background layer
