Tim Janik d4f0062f5e use gdk_pixbuf_new_from_stream(). fixed up item factory so inlined pixbufs
Tue Jun 26 10:04:30 2001  Tim Janik  <timj@gtk.org>

        * gtk/gtkiconfactory.c:
        * gtk/gtkitemfactory.c: use gdk_pixbuf_new_from_stream(). fixed up
        item factory so inlined pixbufs actually work.

Tue Jun 26 09:48:02 2001  Tim Janik  <timj@gtk.org>

        * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf

        * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
        instead from gdk_pixbuf_new_from_inline().

        * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
        installed API for applications that need to serialize/deserialize
        on their own (gimp, BEAST).

        * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
        program that can dump images in CSource format and Pixbuf
        stream format. supports RLE encoding, MACRO formatting etc...
        invoke with --help.
