You attach Camera's directly to the GraphicsWindow, and if you do this then the GraphicsWindow will do the resize of the viewport and (optionally) the projection matrix as well. The on screen stats uses a Camera in this fashion so have a look at the implementation in src/osgViewer/StatsHandler.cpp. If the GraphicsWindow doesn't know about your Camera they you'll need to manage the resize yourself.
