; Changed path (removed "filters/").
|

; 1.03: adds one-pixel border before bumpmapping, and removes it after.
|

; Got rid of the crop-pixel-border option (no longer reqd).
|

; 1.04: Fixed undo handling, ensure that bumpmap is big enough,

|

;
|

; Bumpmap changed arguments from version 2.02 to 2.03. If you use the
|
||||
; wrong bumpmap.c this script will either bomb (good) or produce a
|
||||
; naff image (bad).
|

;
|

; As distributed this script expects bumpmap 2.03 (shipped with Gimp 0.99.11)
