During a first pass, the dimensions are determined, and this happens
locally, which means that in this case a 1 by 1 grid is taken; adding the
third cell kind of obscure this since now the grid is 1 by 3; the solution
is a small patch in m-chart:
\def\getFLOWlocationA#1,#2\end
{\ifnum0#1>\FLOWwidth \xdef\FLOWwidth {#1}\fi
\ifnum0#2>\FLOWheight\xdef\FLOWheight{#2}\fi}
(there are a few more places, but that's not important now)
