* pixbuf-render.c (compute_hint): Optimize the case
where a component is entirely transparent by skipping
drawing it.
* pixbuf-rc-style.c (theme_parse_image): Catch case
where background or overlay border/stretch are specified
without a background image.
* pixbuf-render.c (theme_pixbuf_destroy): Actually free
the structure and filename.
