+INTRODUCTION
+
+A helper module which provides glue to bind the software rasterizer to
+the software t&l module.  The main task of this module is to build
+swrast vertices from the t&l vertex_buffer structs, and to use them to
+perform triangle setup functions not implemented in the software
+rasterizer.
+
+The module implements a full set of functions to plug into the
+t_vb_render.c driver interface (tnl->Driver.Render.*).  
+
+There are strong advantages to decoupling the software rasterizer from
+the t&l module, primarily allowing hardware drivers better control
+over fallbacks, the removal of implicit knowledge about the software
+rasterizer in the t&l module, allowing the two modules to evolve
+independently and allowing either to be substituted with equivalent
+functionality from another codebase.
+
+This module implements triangle/quad setup for offset, unfilled and
+twoside-lit triangles.  The software rasterizer doesn't handle these
+primitives directly.
+
+Hardware rasterization drivers typically use this module in situations
+where no hardware rasterization is possible, ie during total
+fallbacks. 
+
+STATE
+
+To create and destroy the module:
+
+	GLboolean _swsetup_CreateContext( GLcontext *ctx );
+	void _swsetup_DestroyContext( GLcontext *ctx );
+
+The module is not active by default, and must be installed by calling
+_swrast_Wakeup().  This function installs internal swrast_setup
+functions into all the tnl->Driver.Render driver hooks, thus taking
+over the task of rasterization entirely:
+
+        void _swrast_Wakeup( GLcontext *ctx );
+
+   
+This module tracks state changes internally and maintains derived
+values based on the current state.  For this to work, the driver
+ensure the following funciton is called whenever the state changes and
+the swsetup module is 'awake':
+
+	void _swsetup_InvalidateState( GLcontext *ctx, GLuint new_state );
+
+There is no explicit call to put the swsetup module to sleep.  Simply
+install other function pointers into all the tnl->Driver.Render.*
+hooks, and (optionally) cease calling _swsetup_InvalidateState().
+
+DRIVER INTERFACE
+
+The module offers a minimal driver interface:
+
+	 void (*Start)( GLcontext *ctx );
+	 void (*Finish)( GLcontext *ctx );
+	 
+These are called before and after the completion of all swrast drawing
+activity.  As swrast doesn't call callbacks during triangle, line or
+point rasterization, these are necessary to provide locking hooks for
+some drivers.  They may otherwise be left null.
