- Updates the various classes using materials to comply to the change.
- Also standardizes some getter names to follow the general convention image and shape used to keep things more consistent across the board to minimize usage friction.
- Shifts handling of fallback asset lookups for the thus-far converted classes to have them be loaded during core initialization rather than being loaded as part of other asset loading as that sometimes lead to nesting execution/stability errors. Explicit call now ensures the fallbacks are loaded before any other asset tries to load, so there's no room for confounding or having no fallback to work with.
-Added: SkySphere a full sphere skyBox
-Change: ScatterSky now renders a dome instead of the top face of a cubeSphere
-Change: Creator now has skySphere
TODO: Simplify sphere creation
PossibleMethod: Add the sphere creation functions to one place to be shared around.
