Non visible items still cause renders

1. Add a logic box
2. Add an analogue clock inside the logic box
3. Use custom scripting on the box to create two rules:
> If Input 1 Equals 1: Visibility is true
> If Input 1 Does Not Equal 1: Visibility is false
4. You can now show & hide the clock by changing input 1 to 1 or 0 respectively.
5. Notice that whether the clock is hidden or visible the renders/second value 
on the system page is the same

This causes a lot of unnecessary extra work
