Compose Modifier
zIndex
Common
```kotlin
fun Modifier.zIndex(zIndex: Float): Modifier
```
Creates a modifier that controls the drawing order for the children of the same layout parent. A
child with larger `zIndex` will be drawn on top of all the children with smaller `zIndex`. When
children have the same `zIndex` the original order in which the parent placed the children is
used.
Note that if there would be multiple `zIndex` modifiers applied for the same layout the sum of
their values will be used as the final zIndex. If no `zIndex` were applied for the layout then
the default zIndex is 0.
