Fixed #22033.

This JSON file expresses its geometry data as `Geometry`. It can't be loaded with `ObjectLoader` anymore.

Remove unused import.

* Use clamped material.emissiveIntensity at GLTF export

* Revert build

* Revert build (for real)

* Third time's the charm

* Limit the emissive value after multiplying by emissiveIntensity

* Better readability (as suggested by WestLangley)

* NRRDLoader.js now identifies anchor points from within the "space directions" field within an NRRD file to orient and transform the volume structures properly in 3D space, fixing the previously broken sagittal and coronal oriented scans.

* Improved initial solution. Retained most of the core-logic and changed only how the spacing (and thus, the size) is calculated by changing its read target. This is done by storing axis order as a new member of the Volume objects

* Better semantics for spacing.

* Removed extra variables.
