// .NAME vtkRenderPass - Perform part of the rendering of a vtkRenderer.
// .SECTION Description
// vtkRenderPass is a deferred class with a simple deferred method Render.
// This method performs a rendering pass of the scene described in
// vtkRenderState.
// Subclasses define what really happens during rendering.
//
// Directions to write a subclass of vtkRenderPass:
// It is up to the subclass to decide if it needs to delegate part of its job
// to some other vtkRenderPass objects ("delegates").
// - The subclass has to define ivar to set/get its delegates.
// - The documentation of the subclass has to describe:
// - what each delegate is supposed to perform
// - if a delegate is supposed to be used once or multiple times
// - what it expects to have in the framebuffer before starting (status
// of colorbuffers, depth buffer, stencil buffer)
// - what it will change in the framebuffer.
// - A pass cannot modify the vtkRenderState where it will perform but
// it can build a new vtkRenderState (it can change the FrameBuffer, change the
// prop array, changed the required prop properties keys (usually adding some
// to a copy of the existing list) but it has to keep the same vtkRenderer
// object), make it current and pass it to its delegate.
// - at the end of the execution of Render, the pass has to ensure the
// current vtkRenderState is the one it has in argument.
