I've used browser::create_vrml_from_stream successfully, but I can't
understand, which scope got created node.

	field_value_listener< mfnode >& fvl_add =
group_node->event_listener< mfnode >("addChildren");

	std::stringstream sss;
	sss << "DEF main_TS TouchSensor {}";
	mfnode::value_type nodes_for_mfnode =
browser.create_vrml_from_stream(sss);

	mfnode mfn(nodes_for_mfnode);
	fvl_add.process_event(mfn, 0.0);

	...

	node* f_n = root_scope.find_node("main_TS");
	// f_n == 0 :(

TouchSensor is created and works, but created node doesn't appear in
root_scope. Where can I find that? Is there any possibility to manage
this?


Getting back to node_type::create_node(). If we can't use this function
outside library, it would be better to remove this one from public
interface?


Another thing. I've found small bug in openvrml-xembed and
mozilla-plugin interaction. And I don't know how bug-tracking have to be
used, so I write here. =)

openvrml-0.17.6\mozilla-plugin\src\openvrml.cpp : 442
	command << "new-stream " << ptrdiff_t(stream) << ' ' << type <<
' ' << stream->url << '\n';
openvrml-0.17.6\mozilla-plugin\src\openvrml.cpp : 460
	command << "destroy-stream " << ptrdiff_t(stream) << '\n';

Signed type ptrdiff_t is using.

openvrml-0.17.6\src\openvrml-xembed\main.cpp : 149-151
	size_t stream_id;
	std::string type, url;
	command_line_stream >> stream_id >> type >> url;
openvrml-0.17.6\src\openvrml-xembed\main.cpp : 172-173
	size_t stream_id;
	command_line_stream >> stream_id;

Unsigned type size_t is using.

That was reason my system crash during plug-in initialization. This
happens from time to time.
