Observable for engine dispose

[Hersir]

Hi,

I needed to remove some custom logic when 3d app (engine), is disposed, so was trying to find some callback / observable that could indicate engine dispose, but didn’t find any

At the end I used onDisposeObservable from scene, as I have just 1 scene, for me disposing it also means that app is disposed, but that would not work for multi scene scenario.

Just curious if anyone else needs such feature and would it make sense to add it ?

Thank you

If you want to add it no problem for me, I love observables
