      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.
-   - Removed swrast->Driver.SetReadBuffer
-   - Added swrast->Driver.SetBuffer.  This function should be implemented by
-     all device drivers that use swrast fallbacks (and the span functions).
-     Mesa will call this function to specify the buffer to use for span
-     reading AND writing and point/line/triangle rendering.  There
-     should be no confusion between current read or draw buffer anymore.
