Process input queue We always call this with the value of 'bool g.IO.ConfigInputTrickleEventQueue'. - trickle_fast_inputs = false : process all events, turn into flattened input state (e.g. successive down/up/down/up will be lost) - trickle_fast_inputs = true : process as many events as possible (successive down/up/down/up will be trickled over several frames so nothing is lost) (new feature in 1
