* `windows`: contains all visible windows, on mobile it's typically just one or two (e.g. if a dialog is open)
* `type`: The fully qualified widget class name, this name may be obfuscated on certain platforms (e.g. Android release builds with proguard enabled)
* `children` nests all child UI widgets, which then builds up the whole UI tree
* `positioning`: indicates how the element is positioned in relation to its parent. If not supplied, defaults to platform default.

Where do we define the platform default? Can we add a link here?

As per, getsentry/sentry#107507, relative is the default and there is a small list of platforms overriding it.


A typical Android/iOS view hierarchy for a single window consists of around 100-200 objects. Taking the attributes from the example above this generates a raw JSON file with a size of around 50KB. More complex view hierarchies, for example a Unity game, may hold 1000-2000 objects, producing a JSON file of around 500KB.
