Unfortunately it doesn't work. Rendering now fails with an error:
Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
>(nil nil)
(if (> (cdr (nth 2 (posn-at-point))) orig-y) (backward-char 1))
(let ((orig-y (cdr (nth 2 (posn-at-point))))) (vertical-motion (cons (/ column (frame-char-width)) 0)) (if (> (cdr (nth 2 (posn-at-point))) orig-y) (backward-char 1)) (if (eolp) nil (let* ((posn (posn-at-point)) (ch-x (car (nth 2 posn))) (ch-width (car (nth 9 posn))) (ch-pos (nth 1 posn))) (if (and (natnump ch-pos) (<= (+ ch-x ch-width) win-width)) (forward-char 1)))))
(if (not shr-use-fonts) (move-to-column column) (if (eolp) nil (forward-char 1)) (let ((orig-y (cdr (nth 2 (posn-at-point))))) (vertical-motion (cons (/ column (frame-char-width)) 0)) (if (> (cdr (nth 2 (posn-at-point))) orig-y) (backward-char 1)) (if (eolp) nil (let* ((posn (posn-at-point)) (ch-x (car (nth 2 posn))) (ch-width (car (nth 9 posn))) (ch-pos (nth 1 posn))) (if (and (natnump ch-pos) (<= (+ ch-x ch-width) win-width)) (forward-char 1))))))
shr-vertical-motion(1250 1247)
[...]
shr-fill-line()
because `posn-at-point' returns nil as soon as point moves past
`window-end'. I can see that with the
(advice-add 'shr-fill-line :after (lambda (&rest _) (sit-for .5)))
advice active.
Obviously it's not as simple as I thought, not the whole buffer is
"already displayed". My bad.
Michael.
