Each 3D building of the map style lights up under the pointer, takes the click colour when you select it and keeps a paint colour of its own.

• A BaseMapModule click handler scoped to the buildings3D group reports the building under the pointer, its id and its properties. With it listening, the buildings turn the buildings3D.hover and buildings3D.click colours.
• setBuildingColors gives the buildings you name by id a colour of their own, which they keep as their tiles reload. getBuildingIdAt names the building standing at a position, so two towers are coloured from their coordinates, not from ids read off a click.
