The array that contains draw commands to render as the result of the OnPerformCulling call.
This can contain as many commands as necessary, and each command can render multiple instances. The culling callback must allocate the memory for this using Unity.Collections.LowLevel.Unsafe.UnsafeUtility.Malloc with the Unity.Collections.Allocator.TempJob parameter. Unity releases this memory when it finishes rendering the draw commands.
