Called when the Gamemode is about to draw a given element on the client's HUD (heads-up display).
This hook is called HUNDREDS of times per second (more than 5 times per frame on average). You shouldn't be performing any computationally intensive operations.
Return false to prevent the given element from being drawn on the client's screen.
Hides the default health and battery (armor) HUD elements, while still allowing the display of other elements to be controlled by other addons.
