-drivers.
-
-The swrast module 'stands alone', relying only on interfaces to core

-other modules, allowing it to be used for fallback paths in future tnl

-
-As well as providing triangle/line/point rasterization functionality,

-(ReadPixels, etc), and texture operations (CopyTexSubImage) which may

-
-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':
-
