	** Fix for bug #488213

	* e-util/e-icon-factory.h: (e_icon_factory_pixbuf_scale):
	* e-util/e-icon-factory.c: (e_icon_factory_pixbuf_scale):
	New global function for pixbuf scaling which speeds up scaling when
	HAVE_LIBGNOMEUI_GNOME_THUMBNAIL_H.

	* addressbook/gui/contact-editor/e-contact-editor.c: (extract_simple_field):
	* mail/em-icon-stream.c: (emis_fit):
	* mail/em-format-html-display.c: (efhd_attachment_button):
	* e-util/e-icon-factory.c: (load_icon):
	* widgets/misc/e-spinner.c: (scale_to_size):
	* widgets/misc/e-image-chooser.c: (set_image_from_data):
	* widgets/misc/e-attachment-bar.c: (e_attachment_bar_create_attachment_cache), (update):
	Use global function e_icon_factory_pixbuf_scale for scaling pixbufs.
