popuplayout had two refit stages for a work area shorter than one padded row — 40 pixels — and popupdraw re-checked the layout it had just been handed, against an Imgh that bounded no buffer any more. Pango and Cairo abort rather than return nil, so textinit is void and the layout is never nil; the stride Cairo computes for RGB24 is w*4 by definition; and textdraw set the layout's width and ellipsis twice.
