…d() and ViewportSignKdtreeItem::MakeStation()
…or stations Keeping track of whether the ViewportSign data are valid for Kdtree usage allows moving more housekeeping to Station::UpdateVirtCoord and Waypoint::UpdateVirtCoord and helps simplify a lot of other code.

…nates (OpenTTD#7849) Ensure the same coordinates are used for station/town/player signs regardless of how the landscape changes below it after the coordinates were first determined. By keeping track of whether each ViewportSign is valid for Kdtree use (and only ever registering the viewport sign when the object is valid) a lot of code can be simplified and become more robust at the same time.

Fix #7847 by ensuring the same coordinates are used for a station sign regardless of how the landscape changes below it after the coordinates were first determined.
By keeping track of whether the ViewportSign is valid for Kdtree use (and only ever registering the station viewport sign when the sign object is valid) a lot of code can be simplified, and it should prevent a lot of similar bugs too.
I think this is the real solution to all Kdtree bugs regarding station signs. I think something similar needs to be done for town names and player signs too.
