* app/*, po/de.po, de/POTFILES.in, libgimp/gimpintl.h:
Lots of ii8n stuff here and some additions to the de.po.
Applied gimp-egger-981005-1 ,gimp-egger-981006-1,
gimp-egger-981007-1, gimp-egger-981008-1,
gimp-egger-981009-1.patch, gimp-egger-981010-1.patch
* plug-in/guillotine/guillotine.c: added the coordinates
of the split images from the original image to the title.
ie foo.jpg (0,0) for the image in the topleft.
* plug-in/script-fu/scripts/neon-logo.scm,
perspective-shadow.scm, predator.scm,rendermap.scm,
ripply-anim.scm, select_to_image.scm,swirltile.scm,
xach-effect.scm: updated scripts to use new script-fu stuff
wooo boy! a big un!
in testing this, it looks like some of the po files are busted.
but the code stuff seems okay.

Lots of ii8n stuff here and some additions to the de.po. Applied
Wed Oct 14 17:46:15 EDT 1998 Adrian Likins <adrian@gimp.org>
* app/*, po/de.po, de/POTFILES.in, libgimp/gimpintl.h:
Lots of ii8n stuff here and some additions to the de.po.
Applied gimp-egger-981005-1 ,gimp-egger-981006-1,
gimp-egger-981007-1, gimp-egger-981008-1,
gimp-egger-981009-1.patch, gimp-egger-981010-1.patch
* plug-in/guillotine/guillotine.c: added the coordinates
of the split images from the original image to the title.
ie foo.jpg (0,0) for the image in the topleft.
* plug-in/script-fu/scripts/neon-logo.scm,
perspective-shadow.scm, predator.scm,rendermap.scm,
ripply-anim.scm, select_to_image.scm,swirltile.scm,
xach-effect.scm: updated scripts to use new script-fu stuff
wooo boy! a big un!
in testing this, it looks like some of the po files are busted.
but the code stuff seems okay.
