bug#13974: 24.3.50; Height of font is not correct

[Sebastien Vauban]

Hello,

With Emacs 24.3.50, the height factor of my `org-level-1' face is not anymore
respected:

  ╭────

See http://screencast.com/t/OAiQkMVdf for a comparison between Emacs 24.3.1
(where the x 1.3 multiplicative factor works) and Emacs 24.3.50 (where it
doesn't work).

Best regards,
  Seb

PS- I'm using `leuven-theme' (present in Emacs 24.3.50).
