leaving it up to the Viewer to specify the mode (which by default is MultiThreaded).
Added a check for the presence of osgParticle systems so that threading is
disabled in this case.
mouse coords in osgGA::GUIEventAdapter, and ported osgGA camera manaipulators
to use the new normalized values.
Moved osgProducer across to tracking the window dimensions and ensure that the
internals values in osgProducer::EventAdapter are kept consistent. Moved
the warp pointer in Viewer across to using KeyboardMouse::positionPointer().
