    ivy: fix ivy--resize-minibuffer-to-fit for small delta
    
    Very small size increments can be necessary if the initial candidate
    list is short (e.g. 3 items) and line-height is set to something other
    than zero. In that case, only half of the last line is initially
    visible. ivy--resize-minibuffer-to-fit recognizes this and tries to
    enlarge the window up the the exact pixel height required, however
    window-resize doesn't do anything if the delta is below
    frame-char-height.
