When Emacs creates the initial frame and selects the default
font, "(add-to-list ...)" is not yet evaluated, so if your
default fonts is 'Courier New', it is opened without
scaling.

What I currently don't understand is that the font rescaling
doesn't work for the default font in the above case even
after (clear-face-cache t).  I'm now investigating the
reason.
