It's a very common use case to want to convert the position of a nested entity (relative to the parent) to an absolute position relative to the scene's 0,0,0.
Currently in SDK6 we have a function for that in the Utils library, but such a common task should be part of the base SDK, not relying on installing extra libraries.
We need a function to obtain the world position and another to obtain the world rotation.
These functions would take a single entity as an argument, and also allow for a second optional argument to provide an offset, for example getWorldPosition(myEntity, Vector3.create(1,0,0) to get the position immediately in-front of an entity.
In the most simple of cases, we check for parent entities and offset any position, rotation & scale.
But if we're doing this as part of the SDK, maybe we can even do more powerful things engine-side, to include animations too.
For example for entities attached to a player we should involve the player position, and even (nice to have) any translation from player emotes.
