2000-06-21  Havoc Pennington  <hp@pobox.com>

* gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
(i.e. derivation is not allowed, and there are no virtual methods
anyway).
(gdk_pixbuf_preinit): Call g_type_init() here.
(gdk_pixbuf_init): Add a user-friendly init function, for users
of standalone gdk-pixbuf

* gdk-pixbuf-animation.c: Convert to GObject, in the same
way GdkPixbufAnimation was done.

* gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
gdk_pixbuf_finalize() from API, since these are broken and don't
make sense with new GObject stuff.

2000-06-21  Havoc Pennington  <hp@pobox.com>

* gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): Fix bug where
we didn't check window->bg_pixmap != GDK_NO_BG.

* gtk/gdk-pixbuf-loader.c: Change to reflect GObject-ification of
gdk-pixbuf
