-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( struct gl_context *ctx );

-	void _swrast_DestroyContext( struct gl_context *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( struct gl_context *ctx, GLuint new_state );

-

-There is no explicit call to put the swrast module to sleep.  

-

-

-CUSTOMIZATION

-

-   void (*choose_point)( struct gl_context * );

-   void (*choose_line)( struct gl_context * );

-   void (*choose_triangle)( struct gl_context * );

-

-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.
