+; Copyright (C) 1997 Andrew Donkin  (ard@cs.waikato.ac.nz)
+; Contains code from add-shadow.scm by Sven Neumann
+; (neumanns@uni-duesseldorf.de) (thanks Sven).
+;
+; Adds a bevel to an image.  See http://www.cs.waikato.ac.nz/~ard/gimp/
+;
+; If there is a selection, it is bevelled.
+; Otherwise if there is an alpha channel, the selection is taken from it
+; and bevelled.
+; Otherwise the part of the layer inside the image boundaries is bevelled.
+;
+; The selection is set on exit, so Select->Invert then Edit->Clear will
+; leave a cut-out.  Then use Sven's add-shadow for that
+; floating-bumpmapped-texture cliche.
+
+;
+; 1.01: now works on offset layers.
+; 1.02: has crop-pixel-border option to trim one pixel off each edge of the
+;       bevelled image.  Bumpmapping leaves edge pixels unchanged, which
+;       looks bad.  Oddly, this is not apparent in GIMP - you have to
+;       save the image and load it into another viewer.  First noticed in
+;       Nutscrape.
+;       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,
+;       (instead of resizing the image). Removed references to outdated
+;       bumpmap plugin.     (Simon)
+; 1.05  When there is no selection, bevel the whole layer instead of the
+;       whole image (which was broken in the first place).
+;       Also fixed some bugs with setting the selection when there is no
+;       initial selection.     (Barak Itkin)
