[NTG-context] FLOWcharts connection bug

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. (ConTeXt 2004-01-13; TeXLive 7 on WinNT; pdfTeX 1.11a-2.1) 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! ------------------- Henning Hraban Ramm
