Unused parameter in GtkIconFactory

[Jeff Franks <jcf tpg com au>]

Hi,

In the function gtk_icon_set_render_icon the 'GtkWidget* widget'
parameter appears unused. gtk_icon_set_render_icon passes the widget
pointer to gtk_style_render_icon which passes it to
gtk_default_render_icon but none of these functions appear to use it. Am
I missing something?

Thanks,

Jeff
