--
-- NOTHING runs in the caller's execution: the first slice is deferred too,

-- the first frame after the screen drops.

-- handler and the chain CONTINUING: an async chain that died mid-way would

--               position (main chat, whose spot Blizzard's Edit Mode also
--               applies): anchor links never move it and it offers no link or

--    noResize   (boolean) true for Blizzard elements that cannot be resized
--    sizeFixedByLook (boolean) the current look fixes the element's size

--    getBottomExtra (function(key) -> height)  extra height, in the frame's

--               box to the rect the mover outlines (Blizzard Style unit frames)
--    detachedMover (boolean) the frame refuses dependents (it carries a
--               forbidden layout aspect), so the mover takes its screen spot by
--               absolute anchor instead of anchoring to it
--    loadRawPos (function(key)) -> the STORED position table, for an element
