2007-01-30 Michael Natterer <mitch@gimp.org> * app/vectors/Makefile.am * app/vectors/vectors-types.h * app/vectors/gimpvectorspropundo.[ch]: new undo class which implements GIMP_UNDO_VECTORS_REPOSITION. * app/core/gimpimage-undo-push.c: use it here. * app/Makefile.am: another lame linker hack to make it build with the new file that is not used in app/vectors/ itself. svn path=/trunk/; revision=21818
