Thanks.  I hacked up this function:

(defun pixel-region-width (start end)
  (let ((width 0))
    (while (< start end)
      (let ((glyphs (font-get-glyphs (font-at start) start start)))
        (setq width (+ width (aref (car glyphs) 4))))
      (setq start (1+ start)))

But it fails because `font-get-glyphs' always returns nil when I try it.
