// .NAME vtkShadowMapPass - Implement a shadow mapping render pass.
// .SECTION Description
// Render the opaque polygonal geometry of a scene with shadow maps (a
// technique to render hard shadows in hardware).
//
// This pass expects an initialized depth buffer and color buffer.
// Initialized buffers means they have been cleared with farest z-value and
// background color/gradient/transparent color.
// An opaque pass may have been performed right after the initialization.
//
//
//
// Its delegate is usually set to a vtkOpaquePass.
//
// .SECTION Implementation
// The first pass of the algorithm is to generate a shadow map per light
// (depth map from the light point of view) by rendering the opaque objects
// with the OCCLUDER property keys.
// The second pass is to render the opaque objects with the RECEIVER keys.
//
