+**
+** regArg:
+**   Each window function requires an accumulator register (just as an
+**   ordinary aggregate function does). This variable is set to the first
+**   in an array of accumulator registers - one for each window function
+**   in the WindowCodeArg.pMWin list.
+**
+** eDelete:
+**   The window functions implementation sometimes caches the input rows
+**   that it processes in a temporary table. If it is not zero, this
+**   variable indicates when rows may be removed from the temp table (in
+**   order to reduce memory requirements - it would always be safe just
+**   to leave them there). Possible values for eDelete are:
+**
+**      WINDOW_RETURN_ROW:
+**        An input row can be discarded after it is returned to the caller.
+**
+**      WINDOW_AGGINVERSE:
+**        An input row can be discarded after the window functions xInverse()
+**        callbacks have been invoked in it.
+**
+**      WINDOW_AGGSTEP:
+**        An input row can be discarded after the window functions xStep()
+**        callbacks have been invoked in it.
+**
+** start,current,end
+**   Consider a window-frame similar to the following:
+**
+**     (ORDER BY a, b GROUPS BETWEEN 2 PRECEDING AND 2 FOLLOWING)
+**
+**   The windows functions implmentation caches the input rows in a temp
+**   table, sorted by "a, b" (it actually populates the cache lazily, and
+**   aggressively removes rows once they are no longer required, but that's
+**   a mere detail). It keeps three cursors open on the temp table. One
+**   (current) that points to the next row to return to the query engine
+**   once its window function values have been calculated. Another (end)
+**   points to the next row to call the xStep() method of each window function
+**   on (so that it is 2 groups ahead of current). And a third (start) that
+**   points to the next row to call the xInverse() method of each window
+**   function on.
+**
+**   Each cursor (start, current and end) consists of a VDBE cursor
+**   (WindowCsrAndReg.csr) and an array of registers (starting at
+**   WindowCodeArg.reg) that always contains a copy of the peer values 
+**   read from the corresponding cursor.
+**
+**   Depending on the window-frame in question, all three cursors may not
+**   be required. In this case both WindowCodeArg.csr and reg are set to
