Need <Splat> loaded boolean

[NORXONDOR]

Describe the feature you'd like:

I want Splat to have a boolean, which when all positional data has been loaded, gets set to True. Code can then monitor when this updates and then read all of the positional data to generate something like the boundingBox for the model, instead of checking something like the last value of centerAndScaleTexture.source.data.data to determine if positional data has been set (my current implementation).

Better yet, an in-built boundngBox/Sphere calculation and attribute would be nice, as that is for what I am using the positional data.

Suggested implementation:

It seems like positional data is loaded in pushDataBuffer(). If this could set a shared boolean to True, it would fix this. If you want some help for the boundingBox calculation code, I am happy to provide.
