* 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
- Use polygon as data source for intersection
- Add padlock icon
- Show padlock icon on read only polygons
- Add Fwk function appendMenuItems() to make it possible to define context menu content in a PdmObject
- Context menu "Create Polygon Intersection"
- Updates to make visualization consistent with object and object collection enabled state
* Refactor interface to PdmObjectHandle and PdmFieldHandle
Return objects instead of passing in structures as parameters
* Add nodiscard to several functions
* Remove redundant this->
* Rename to ptrReferencedObjectsByType
* Implement a simple depth filter to cut all geometry below a certain level for intersections
* Add option to override all curve intersection cut depths from collection.
* Add support for showing intersection above or below threshold. Update label texts.
