Parallax occlusion mapping marches the view ray through the height field to find where it meets
the displaced surface. This costs more than [PARALLAX_OFFSET](https://api.playcanvas.com/engine/variables/PARALLAX_OFFSET.md), but represents deeper
displacement without smearing the texture.

```ts
const PARALLAX_OCCLUSION: "occlusion" = 'occlusion'
```
