** SpecialRenderInfoClass
** This structure also contains a "grab-bag" of junk for use by the Special_Render
** function. The first use that I have for Special_Render is to implement the
** visibility detection algorithm where each object is rendered in such a way
** that I can get the 'id' of the object which generated each pixel on the screen.
** Another use I have planned for Special_Render is a shadow rendering mode that
** just draws an object in solid black from the point of view of a light source.
** This would just need another enum for the RenderType...
**
** The reason for a Special_Render function is that I didn't want to pollute
** the main rendering pipeline with checks for these alternate rendering operations.
