Special Light

A special light source is a level object which doesn't define any geometric data. However, it allows the user to use any geometric object as a source of light; all sub objects radiate light. If the sub object is a single point, a point light is achieved. By using a NURBS curve as a sub object, one can create one dimensional area lights. Using a rectangle creates a two dimensional area light. The colors of sub objects of a special light sources are taken into account, including texture mapped colors in a 'Light properties' shader.
