void HudPushState()

This is a HUD Library function.

Saves current HUD Library State to state stack.

If the stack is full, a LimitError is emitted.

HudPushState();
// Change state
HudPopState(); // Back to saved state.

This function is not affected by current HUD Library state and doesn't overwrite it:

function DrawSomething(void)
{
    HudPushState();
    HudResetState();
    ...
    HudPopState();
}
