1999-10-27 Havoc Pennington <hp@pobox.com> * src/gdk-pixbuf.c (gdk_pixbuf_new): New function to create a blank pixbuf. * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Check all three progressive load funcs are non-NULL, rather than checking begin_load three times. Also, check whether begin_load returns NULL on failure.
