[openvrml-develop] Displaying more than one VrmlViewer on the same window

[<luc...@li...>]

I managed to do it:

the trick is to save a safe DC and RC for the current window and then 
adding the following to the window drawing routine:

if (m_pViewer)
	{
		::wglMakeCurrent(m_hDC,m_hRC);
		m_pViewer->redraw();
		
	}.

While writing this code i have seen thing that seems a bug: if i pass 
to the vrmlscene constructor a wrong filename i dont get any message 
error and the vrml world is displayed as empty.
