The view offset, calculated by the Edge Pan system, only affects the
position of the nodes, but forget to update:
- snapping data
- final value of transform
- values used for custom drawing
Therefore, to avoid having to update a lot of scattered data, the
`transformViewUpdate` utility has been implemented to recalculate input
values when the view changes.
This utility does more than is necessary to fix the bug, but with that,
it can work in any situation.
