- * 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).

- * We think that most hardware implementations of DBE will want
- * LookupID*(dbe_back_buffer_id) to return the window structure that the
- * id is a back buffer for. Since both front and back buffers will
- * return the same structure, you need to be able to distinguish
- * somewhere what kind of buffer (front/back) was being asked for, so
- * that ddx can render to the right place. That's the problem that the
- * following code solves. Note: we couldn't embed this in the LookupID*
- * functions because the VALIDATE_DRAWABLE_AND_GC macro often circumvents
- * those functions by checking a one-element cache. That's why we're
- * mucking with VALIDATE_DRAWABLE_AND_GC.
- *
- * If you put -DNEED_DBE_BUF_BITS into PervasiveDBEDefines, the window
- * structure will have two additional bits defined, srcBuffer and
- * dstBuffer, and their values will be maintained via the macros
- * SET_DBE_DSTBUF and SET_DBE_SRCBUF (below). If you also
- * put -DNEED_DBE_BUF_VALIDATE into PervasiveDBEDefines, the function
- * DbeValidateBuffer will be called any time the bits change to give you
- * a chance to do some setup. See the DBE code for more details on this
- * function. We put in these levels of conditionality so that you can do
- * just what you need to do, and no more. If neither of these defines
- * are used, the bits won't be there, and VALIDATE_DRAWABLE_AND_GC will
- * be unchanged. dpw
