      Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and
      leave ctx->Draw.ReadBuffer NULL.
      DRI drivers should implement their own function for ctx->Driver.DrawBuffer
      and use it to set the current hardware drawing buffer.  You'll probably
      also want to check for GL_FRONT_AND_BACK mode and fall back to software.
      Call _swrast_DrawBuffer() too, to update the swrast state.

-   - Added swrast->Driver.SetBuffer.  This function should be implemented by

    This is part of an effort to remove all GLchan types from core Mesa so
