#+begin_src elisp
(require 'svg)
(let* ((text "Hello, world")
(w (* (length text) (window-font-width)))
(h (window-font-height))
(svg (svg-create w h)))
(svg-rectangle svg 0 0 w h :stroke "black" :fill "none")
(svg-text svg text
:x 0
:y (- h 4) ;; Why 4 here?
:fill "black")
(insert-image (svg-image svg :scale 1 :ascent 'center)))
#+end_src
My question is why it uses 4 rather than other number?
#+begin_src elisp
(list (window-font-width)
(window-font-height))
;; => (10 21)
#+end_src
on my machine with 1920x1080 screen resolution.
