// For the script to receive an event when the user presses a hand-controller button, we need to map
// that button to the handler, which we do at the bottom of this script. However, doing so changes
// the mapping for the user, across all scripts. Therefore, we just enable the mapping when going
// "away", and disable it when going "active". However, this is occuring within a Controller event, so we
// have to wait until the Controller code has finished with all such events, so we delay
// it. Additionally, we may go "away" on startup, and we want to wait until any other such mapping
// have occured, because only the last remapping wins.
