	* app/core/gimpimagefile.c: implemented thumbnail loading according
	to the latest version of the Thumbnail Managing standard.

	* app/widgets/gimpimagefilepreview.[ch]: draw a GTK_DIALOG_QUESTION
	pixbuf when no preview is available. The implementation is a bit ugly
	but we can improve this later when GimpPreview has been generalized
	to accept pixbufs also.

	* themes/Default/gtkrc: register the icons for GtkWidget instead of
	GtkImage so they can be used from other widgets too.

	* plug-ins/common/zealouscrop.c: merged fix for bug #71795 from
	stable branch.
