Michael Natterer 83b215f9ea define GDK_PIXBUF_H_INSIDE around including all other headers.
2008-05-28  Michael Natterer  <mitch@imendio.com>

	* gdk-pixbuf.h: define GDK_PIXBUF_H_INSIDE around including all
	other headers.

	* gdk-pixbuf-animation.h
	* gdk-pixbuf-core.h
	* gdk-pixbuf-enum-types.h.template
	* gdk-pixbuf-features.h.in
	* gdk-pixbuf-io.h
	* gdk-pixbuf-loader.h
	* gdk-pixbuf-simple-anim.h
	* gdk-pixbuf-transform.h: add single-include guards that #error
	out if GDK_PIXBUF_DISABLE_SINGLE_INCLUDES is defined and any of
	these files is included individually.

	* gdk-pixbuf-private.h: don't incude "gdk-pixbuf-io.h".

	* gdk-pixbuf-csource.c: #define __GTK_H_INSIDE__ around including
	"../gtk/gtkversion.h". Ugly but needed in this special case.
