Welcome aboard, gdk-pixbuf.

Wed Jun 21 16:38:13 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk-pixbuf/* docs/reference/gdk-pixbuf/*: Welcome aboard,
	gdk-pixbuf.

	* gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
	fixups for GObject.

	* gdk/Makefile.am gdk/gdkpixbuf-render.[ch] gdk/gdkpixbuf.[ch]: Bits of
	gdk-pixbuf with GDK dependencies moved into GDK.

	* gtk/Makefile.am gtk/gdk-pixbuf-loader.[ch]: Temporarily
	move gdk-pixbuf-loader here until GObject has signals.

	* demos/: New directory of demos. Move demos from
	gdk-pixbuf here.

	* demos/pixbuf-init.c: Small bit of code to check for
	loaders in ../gdk-pixbuf/.libs/gdk-pixbuf, and if found,
	set GDK_PIXBUF_MODULEDIR appropriately.

	* gdk/gdkcompat.h: Remove GDK_DRAWABLE_PIXMAP compat
	define which no longer makes sense.
