Better Indication of Input/Output from Space View#1964

When pasting blueprints it’s hard to tell in what direction they are facing.

1. Maybe we could get some visual clue in form of arrows seperated by input/output level.
2. Maybe add 4th layer only for decorations and make them more contrasting to copied tile view.

Launchers at the edge of the platform have arrows. If those all point to the same direction that arrow should be visible when zoomed out beyound the point that buildings don’t render anymore.
