Class
Common
```kotlin
class LayoutBoundsHolder
```
An object which holds on to a (potentially) mutating `RelativeLayoutBounds` of a specific node.
This is meant to be used alongside the `layoutBounds` modifier and `onVisibilityChanged` modifier
in situations where you want to understand he visibility of a node with respect to a specific
viewport instead of with the window.
## Properties
Common
```kotlin
@get:FrequentlyChangingValue
var bounds: RelativeLayoutBounds?
```
The bounds of the node this holder is referencing. This is backed by
`androidx.compose.runtime.MutableState` and might change frequently, so reading it during
composition directly is discouraged.
