-INTRODUCTION
-
-Mesa's native software rasterizer.  This module provides the fallback
-paths for rasterization operations and states that aren't accelerated
-in hardware drivers, and as the full rasterization engine in software
-drivers.
-
-The swrast module 'stands alone', relying only on interfaces to core
-mesa and it's own driver interface.  It knows nothing about the tnl or
-other modules, allowing it to be used for fallback paths in future tnl
-schemes without modification.
-
-As well as providing triangle/line/point rasterization functionality,
-the module provides implementations of the pixel operations
-(ReadPixels, etc), and texture operations (CopyTexSubImage) which may
-be plugged in to the core Mesa driver interface where accelerated
-versions of these operations are unavailable.
-
-
-STATE
-
-To create and destroy the module:
-
-	GLboolean _swrast_CreateContext( GLcontext *ctx );
-	void _swrast_DestroyContext( 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 _swrast_InvalidateState( GLcontext *ctx, GLuint new_state );
-
-There is no explicit call to put the swrast module to sleep.  
-
-
-CUSTOMIZATION
-
-   void (*choose_point)( GLcontext * );
-   void (*choose_line)( GLcontext * );
-   void (*choose_triangle)( GLcontext * );
-
-Drivers may add additional triangle/line/point functions to swrast by
-overriding these functions.  It is necessary for the driver to be very
-careful that it doesn't return an inappropriate function, eg a
-rasterization function in feedback mode.  See the X11 driver for
-examples.
-
-DRIVER INTERFACE
-
-The swrast device driver provides swrast primarily with span- and
-pixel- level interfaces to a framebuffer, with a few additional hooks
-for locking and setting the read buffer.
-
-See the definition of struct swrast_device_driver in swrast.h.
