Retrieves the source pixbuf, or %NULL if none is set.
In addition, if a filename source is in use, this
function in some cases will return the pixbuf from
loaded from the filename. This is, for example, true
for the GtkIconSource passed to the #GtkStyle render_icon()
virtual function. The reference count on the pixbuf is
not incremented.
