Hello Hans and everyone!
Every connection whose origin is the bottom of a cell
and that goes somewhere upwards, draws first up into the cell.
Connections from bottom to bottom cause always a metapost
error.

Some nice-to-have features of FLOWchart connections would be:
- crossing vertical lines should draw an bow at the crossing
(configurable)
- force a line to go via some point (cell coordinate) or several
points instead shortest way
- parallel lines should draw side by side
Herzliche Grüße!
