virtual void	cull ()
	Method called by ViewDependentShadowTechnique to allow ViewData do the hard work computing shadows for its associated view.
virtual void	dirty (bool flag)
	Dirty is called by parent ViewDependentShadowTechnique to force update of resources after some of them were modified in parent technique.
	ViewData ()
	Simple constructor zeroing all variables.
