From Wang Rui, "For a long time, the osgviewerMFC example uses addSlave() to setup the

graphics context and link it with a slave camera. I don't know the
reason we perform like that, which will cause a problem that the
GUIEventHandler may not obtain correct window coordinates because the
main camera will use a default input range to receive events from the
slave camera's graphics context. It is also weird to see the
addSlave() used in non-cluster applications, which beginners will be
confused with.

I've make a slightly modification to the osgviewerMFC example to make
it work without setting slave cameras. I've tested with the MDI
framework and everything seems fine."
