/**
|
|
** BWRenderClass
|
|
** This class implements a simple black-and-white triangle rasterizer which
|
|
** can be used to generate shadow textures. It is faster than a general purpose
|
|
** software renderer due to the fact that no z-buffering or sorting is needed and
|
|
** texturing isn't supported.
|
|
** (gth) 04/02/2001 - I'm going to add render-to-texture code to Renegade so this
|
|
** class may be obsolete.
