; 1999-12-01 First version.
; 2000-02-19 Do not discard the layer mask so that it can still be edited.
; 2000-03-08 Adapted the script to my gimp-edit-fill changes.
; 2000-04-02 Split the script in two parts: one using text, one using alpha.
; 2000-05-29 More modifications for "Alpha to Logo" using a separate function.
;
; To do: use a channel mask for creating the bands, instead of working in the
; image. gimp-invert would then work on one grayscale channel instead of
; wasting CPU cycles on three identical R, G, B channels.
