Hi, when i run the osgkeyboardmouse example in OSG2.2.0 with "fountain.osg"
model, it was quite right in "LineSegmentIntersector" mode, but while i pressd
the 'P' key to switch to "PolytopeIntersector", then it was terminated by
assert! But, when i run it with "cow.osg" model or else, it was OK,
I would contact Paul at Skew-Matrix or Bob they do training on site as
well...

Zoom: change the field of view without changing the camera position, for
example, when a photographer uses a zoom lens. This is possible in both

Pan forwards and backwards
