* Add RivSurfaceIntersectionCurveTools for shared surface intersection curve geometry
* Move the surface intersection collection to RimIntersection
* Add surface curtain footprints for the box and i/j/k intersections
* Build surface intersection curves for the box and i/j/k intersections
* Follow the pillar tilt when projecting a surface onto an intersection
* Estimate the surface intersection by continuing the pillar past the curtain
* 10675 Fix missing intersection line geometry
* Change to list of visible surface intersection lines
* Enable surface intersection band for any intersection
* Show labels for intersection curves in 3D
The polylines are defined in the display coordinate system without Z-scaling. The z-scaling is applied to the visualization parts using Part::setTransform(Transform* transform)
The annotation objects are defined by display coordinates, so apply the Z-scaling to the coordinates.
* Improve naming of surfaces
* Use scaling factor of 1.0 for flat intersection views
