Hi Gadalia,

The OSG doesn't culling per Camera with each camera's own view frustum used
for culling, this means the shadow camera should only cull things that are
in it's frustum.  If it's culling objects that you think should be in the
frustum then perhaps it's just set up with the wrong projection matrix
