Location of precedence contraints not saved with SSIS packages, and no auto arrange
When designing SSIS package control flows, one can move the precedence contrains
around to create an easy to view layout, where the precedence constraints do NOT
overlap tasks (which looks confusing.)
This arrangement of precedence constraints is however not saved with the package -
after saving & reopening the package all precedence constraints goes back to a default
position, usually overlapping tasks.
Since the default layout is so bad (the overlaps), and there is no "auto arrange" that
does a better job, this is to me a bug.
