```kotlin
public class SpatialMoveStartEvent(
    public val pose: Pose,
    public val scale: Float,
    public val size: IntVolumeSize,
)
```

An event representing the start of a move event.

This is expected to trigger when the user first starts moving the movable element and should only
be called once per move action.

 composable, factoring in shrinking or stretching due to [scale](/jetpack-compose/androidx.xr.compose/compose/functions/scale).
