The storage coordinate is left unchanged and is kept as `ReflectionProbeAtlasCoordinate`. A new structure `ReflectionProbeCoordinate` contain scale and offset for efficient sampling without integer math. The `ReflectionProbeWriteCoordinate` is only used during the octahedral map processing. This also has the benefit to centralize the coordinate changes to a single class.
