themes/Default/images/Makefile.am removed ...
2004-08-04 Sven Neumann <sven@gimp.org> * themes/Default/images/Makefile.am * themes/Default/images/stock-brush-generated-*-16.png: removed ... * themes/Default/images/stock-shape-*-16.png: ... and added back with more generic names. * libgimpwidgets/gimpstock.[ch] * app/widgets/gimpbrusheditor.c: changed accordingly. * app/tools/gimpinkoptions-gui.c: use the new stock icons here as well. * app/widgets/Makefile.am * app/widgets/widgets-types.h * app/widgets/gimpblobeditor.[ch]: added a simple blob shape editor widget factored out of app/tools/gimpinkoptions-gui.c.
