Comment 4 for bug 655340

There are several bugs here in play, some already reported:

- connectors inside transformed groups (each layer is translated, if the page has been resized)
- connectors between groups that contain transformed objects with a matrix
- connector lines avoiding shapes unpredictable unless using orthogonal connectors (afaik not yet filed separately)
- connector lines ignore straight 'z' segments closing shapes/paths

most of the issues occurring in the file have been reported earlier:
Bug #556467 “connectors between groups misplaced (regression)”
Bug #576815 “after resizing document beyond the default A4 page size, moving connectors becomes buggy”
Bug #591586 “[connectors] 'z' segments closing a path are ignored”
Bug #617810 “Connector markers alignment to group depends on orientation (should be invariant)”
Bug #620486 “connector lines groups misplaced when opening 0.47 file in 0.48”
