* examples/*/Makefile (CFLAGS): add deprecation guards. * docs/tutorial/gtk-tut.sgml, examples/*/*.c: make most examples deprecation-clean; the major offenders right now are the examples that make heavy use of completely deprecated or broken widgets: list, tree, text, pixmap, paned and progressbar. These will have to be redone from scratch. * demos/Makefile.am (INCLUDES): add -DGDK_PIXBUF_DISABLE_DEPRECATED.
