for that you can patch mp-tool.mpxl (l 676):
maximum := max (xpart llcorner mask, xpart urcorner mask, ypart
llcorner mask, ypart urcorner mask) ;
minimum := min (xpart llcorner mask, xpart urcorner mask, ypart
llcorner mask, ypart urcorner mask) ;
% a hack:
maximum := maximum + max(xpart urcorner shape, ypart urcorner shape);
minimum := minimum - max(xpart urcorner shape, ypart urcorner shape);
a bit overkill but it seems to work
