[osg-users] Hide mouse cursor from CameraManipulator

[Robert Osfield]

HI Bernard,

The osgViewer::View class subclasses from osgGA::GUIActionAdapter, and
this view is passed on during the event traversal to the event
handler/camera manipulators as the event adapter objects, so you just
need to do a dynamic_cast to get back a View pointer and from the View
you can get the list of GraphicsContext/Windows associated with it.
Then for each of the windows attached to the View you can toggle the
cursor.

Robert.
