[osg-submissions] osgconv --compressed not working under MSVC

[Robert Osfield]

Hi Luigi,

This problem suggest that the auto registration of of the
GraphicsWindowWin32 is not working, could it be that Windows is
ignoring the linking of osgViewer until a symbol from it is used in an
application?

Adding osgViewer::Viewer viewer to osgconv (or osgdem for that matter)
is really the wrong way to go about getting the compiler to properly
link to osgViewer.  If we have to pull in something it really should
at least be something relevant to the app.  I wonder if just including
a header would be enough?

Robert.
