other correct me if I am wrong, frustum is map on interval [0, XWindowSize]
and [0, YWindowSize]
Frustums for the cameras:
> master={-50, 0, -40, 40}

during update of camera position, the projection matrix for slaveis compute
as this
slaveCamera->setProjectionMatrix( masterCamera->getProjectionMatrix() *
slaveCamera->getProjectionOffset() );
idem for the view matrix and the viewOffset.
The offset is needed in call to addSlave(osg::Camera* camera,const
