2005-01-07 Shlomi Fish <shlomif@iglu.org.il> * plug-ins/script-fu/scripts/frosty-logo.scm: made sure the shadow is given enough space and then truncated instead of translated to the center of the image, thus preventing the display of shadows with a completely horizontal or vertical edge. Fixes bug #132145.
