[EPIC] Lanes / paths _inside_ building assets

[originalfoo]

These issues relate to lanes or ped paths inside building assets. For clarification: They appear as purple lines in the asset editor.

TM:PE seems to be generally bad at dealing with routes inside buildings.

• Bus routes should respect 1 way routes in buildings #10 - Bus routes should respect 1 way routes in buildings
• Pedestrians not keen on using asset-defined pedestrian routes #174 - Pedestrians not keen on using asset-defined pedestrian routes
  • I also wonder if there might be an issue with paths in sub-buildings (lots of train station assets use sub-buildings or even props to provide their walkways between platforms)

Not technically a 'purple path', but it seems TM:PE prefers cims crossing train tracks rather than using internal paths provided by the station:

• Pedestrians see train track junctions as valid crossing points #188 - Pedestrians see train track junctions as valid crossing points
  • Note also: There are some station designs (see last screenshot) that expect cims to cross the tracks! Not sure how that is implemented.
  • In cases where a pedestrian or bike path (either via "purple line" or network prefbs) crosses train tracks, could we do something akin to an invisible mini-level crossing or traffic lights so that the cims don't run in front of, or through, trains?

And, seeing as we're talking about cim routing through train stations:

• Strange behavior when using multi rail train stations #157 - Strange behavior when using multi rail train stations

Not sure if useful, but while looking at something else I noticed that NetAI (which can be accessed via NetInfo.m_netAI) contains this:

GetNodeBuilding(ushort nodeID, ref NetNode data, out BuildingInfo building, out float heightOffset)
