Having just migrated from an iMac24 to a iMac27 (i7) the screen res
increase (now c.109 ppi) has made the font in script editor and
elsewhere, bordering on unreadable.

The font in script editor on the 24 display looks like Lucida Grande 11
pt ; on the 27 display (although of course it is still Lucid 11 pt) it
is effectively more like 9 pt on the 24 display. Each line is smaller
in real space, by doing some simple measurements of the same text
strings on screen, and replicate text in an editor to compare fonts, it
is easy enough to deduce the comparative font size. So in real space a
2 pt font size decrease.

Is there any means of resetting/hacking the FM font size (libs, prefs...)?
