vtkCuller - a superclass for actor cullers

Description:

A culler has two methods called by the vtkRenderer - OuterCullMethod and InnerCullMethod. The outer method is called before the actor render loop in UpdateActors, and it allows the culler to do some processing on the actors and to modify their AllocatedRenderTime and re-order them in the actor list. The inner method is called right before the actor is rendered and give the culler one last chance to set the actor's allocated render time to 0.0 (meaning that it shouldn't be rendered). A view frustum culler would have an outer method, and no inner method. A visibility culler would have an inner method, and no outer method.
