-%   For \texttt{(x)dvipdfmx} the is a bit more to do yet. Using
-%   \texttt{pdf:bcontent}/\texttt{pdf:econtent} for scoping seems the easiest
-%   approach, but only works reliably when  all of the specials used are
-%   \texttt{pdf:\ldots} ones. As (some) PostScript specials can also be used
-%   with \texttt{(x)dvipdfmx}, that is not safe and can give unexpected output.
-%   To get everything in the right place, what is required is that the
-%   insertion point for the clip and the \TeX{} box material are the same. That
-%   is done by flipping the axes twice with an additional scope level in
-%   between. The scoping level moves to the \enquote{current point}, which 
-%   due to the axis inversion is the \emph{start} of the clip. The second
-%   inversion puts things back to normal, the \TeX{} material is inserted and
-%   then the extra scope is closed (below).
