// .NAME vtkLightActor - a cone and a frustum to represent a spotlight.
// .SECTION Description
// vtkLightActor is a composite actor used to represent a spotlight. The cone
// angle is equal to the spotlight angle, the cone apex is at the position of
// the light, the direction of the light goes from the cone apex to the center
// of the base of the cone. The square frustum position is the light position,
// the frustum focal point is in the direction of the light direction. The
// frustum vertical view angle (aperture) (this is also the horizontal view
// angle as the frustum is square) is equal to twice the cone angle. The
// clipping range of the frustum is arbitrary set by the user
// (initially at 0.5,11.0).
// .SECTION Caveats
// Right now only spotlight are supported but directional light might be
// supported in the future.
