[osg-users] Invisible light points

[Robert Osfield]

Hi Andreas,

A test that I've just done was to add a return to the
Geometry::drawImplementation() to prevent it from doing vertex array setup
or dispatching any primitives sets, doing this allows the Lightpoits to
appear.  This indicates either GL state or osg::State internal settings
aren't being managed correctly somewhere in the mix.

Robert.
