And an update for developers: try C-x C-e behind the following

(display-mm-height)                ;; 203 on my 13.3" display
(display-pixel-height)             ;; 768 here
(face-attribute 'default :height)  ;; 150 here

Note that the face attribute is specified in tenths of PostScript

I use this data to calculate the pixel height of graphics supposed to
fit the size of the default font.

What output do you Carbonized hackers get?
