Subject: [PATCH] Adjust latency position depending on time visibility

Latency placement is no longer fixed:
* If time is visible, it is placed on top of the screen and latency is placed below
* If time is not visible, latency is placed on top of the screen
Both are displayed on alternative HUD only
