-- Input:  every device the engine can see, its kind, slot and identity, the live state of every
-- axis and button of each, the dead zone and trigger threshold in force, and whether the stick is
-- driving the mouse.  Every device Singe opens is a gamepad, an unrecognised one through a mapping
-- Singe writes for it, so there is one family to report and not two.
--
-- The phases are timed on the wall clock so a test harness can attach a device, press something on
-- it and take it away again while the scene is running.
