`font-at' doesn't seem to like to be called in buffers that aren't
displayed in a window:

    (insert (propertize "foo" 'face 'variable-pitch))
    (font-at (point-min)))


Debugger entered--Lisp error: (error "Specified window is not displaying the 
current buffer")
  (progn (insert "foo") (font-at (point-min)))
  (unwind-protect (progn (insert "foo") (font-at (point-min))) (and 
(buffer-name temp-buffer) (kill-buffer temp-buffer)))
  (save-current-buffer (set-buffer temp-buffer) (unwind-protect (progn (insert 
"foo") (font-at (point-min))) (and (buffer-name temp-buffer) (kill-buffer 

shr uses temporary buffers to format various bits, so this doesn't seem
to be a practical approach when determining the pixel widths of text.
