 /******************************************************************************
  *
- * DBE DIX Procedure: DbeValidateBuffer
- *
- * Description:
- *
- *     This function is called from VALIDATE_DRAWABLE_AND_GC and from
- *     various places in dispatch.c if the server has been compiled with
- *     the flags -DNEED_DBE_BUF_BITS and -DNEED_DBE_BUF_VALIDATE.  
- *     When pWin->dstBuffer changes, this function will be called with pWin
- *     as the first argument, the drawable ID that was specified as the
- *     second argument (could be a back buffer id), and True for the third
- *     argument.
- *     When pWin->srcBuffer changes, the third argument will be False, and
- *     the first two arguments are as described for dstBuffer.
- *
- *     This function should prepare the hardware to access the specified
- *     buffer for reads (if dstbuf is False) or writes (if dstbuf is True).
