Function
updateLayerBlock
Common
```kotlin
fun LayoutModifierNode.updateLayerBlock(layerBlock: (GraphicsLayerScope.() -> Unit)?)
```
Updates the layer block of the `LayoutModifierNode`. This will mark the layer as invalidated and
schedule a refresh of the layer.
Updating the layer lambda using this method is cheaper than invalidating placement and placing
the layout with a new layer block. This API is expected to be used alongside `Placeable.placeAt`
with a `layerBlock` parameter passed. This will override/update the layerBlock passed in that
API. Whichever one was called last should "win".
#### Parameters

| --- | --- |
| layerBlock | the snapshot-observed lambda used to set properties on the layer. if `null`, is provided it will remove the layer. |
