[osg-submissions] shared points (between OSG and the application using OSG)

[Mike Garrity]

There was an on again/off again thread on OSG users about 
creating subclasses of osg::Array that referenced data 
stored an application's internal data structures. I took 
a stab at implementing that and ran into a couple of 
downcasts in Geometry.cpp. Enclosed is my take at fixing 
those along with a simple example of how to do this.
