 * $Log:: /JP2_PC/Source/Lib/Renderer/ScreenRenderShadow.cpp                                   $
 * 
 * 11    1/12/98 11:46a Pkeet
 * Added in the software lock request for the auxilary renderer.
 * 
 * 10    97/11/08 3:48p Pkeet
 * Removed Z template parameters and code.
 * 
 * 9     97/06/27 15:38 Speter
 * Changed CGouraudOff to CGouraudNone where appropriate. 
 * 
 * 8     6/19/97 2:53p Mlange
 * Moved Profile.hpp to Lib/Sys.
 * 
 * 7     97/06/17 2:03p Pkeet
 * Removed the reference counting pointer from prasScreen.
 * 
 * 6     97/05/23 17:35 Speter
 * Updated CScreenRenderShadow for new CDrawPolygon.
 * 
 * 5     97/05/13 13:40 Speter
 * Renamed SRenderTriangle::seterfTri to seterfFace.
 * 
 * 4     97-05-06 16:09 Speter
 * Updated, simplified, for new parallel-capable CCamera.
 * 
 * 3     97-04-04 12:38 Speter
 * A big change: now pipeline uses CRenderPolygon rather than SRenderTriangle (currently always
 * as a triangle).  Changed associated variable names and comments.
 * 
 * 2     97-04-02 19:12 Speter
 * Changed interface to match new DrawTriangles() taking array of pointers, fixing shadows.
 * 
 * 1     97-03-28 17:00 Speter
 * Rasteriser specialised/simplified for shadow buffering.
