Updates to work with GTK+-2.0 theme engine architecture. It won't even

Browse Source 
Tue Jul 18 12:13:19 2000  Owen Taylor  <otaylor@redhat.com>

        Updates to work with GTK+-2.0 theme engine architecture.
	It won't even sort of work with GTK+-1.2 any more.

	* configure.in src/Makefile.am: Look for GTK+-2.0,
	install engine into GTK+-2.0 location.

	* src/pixbuf-style.h src/pixbuf-rc-style.[ch]: New
	files for GtkRcStyle and GtkStyle subclasses. Parsing,
	etc, moves to pixbuf-rc-style.[ch]

	* src/pixbuf-draw.c: Chain up to parent implementation
	when images aren't found for a certain element.
