fix: Cleans up Point checks and removes statics (#966)

- [X] Removes static freezing/unfreezing. Use other tools for this.
- [X] Cleans up IPoint3D allocations
- [X] Removes IPoint3D constructors since the compiler may not optimize the constructor path and allow allocations.


Note: Instead of `new Point3D(m)`, do something like `new Point3D(m.Location)`. Sorry for the inconvenience. In the long run this will prevent abuse of hot paths that will cause performance issues.
