Handle invisible nodes in emit_node. Otherwise, style=invis has to
go into the HTML label code, plus gvrender_usershape so that images
in invisible nodes aren't drawn.
The only changes in semantics is that we no longer emit map data for
invisible nodes. If someone can make a case that invisible nodes should
be sensitive, we can go the more complex route.
