Ok.. another option:

No migration
No file-format bumps / syntax changes

Hard code a 1.3x scale factor between gschem font units and points, both
on-screen and for print.

This means schematics will print with their text a bit larger, but
matching on-screen rendering.

Old schematics will render roughly the same on screen - albiet with text
taking up a little less width. (See large vs. medium boxes in my last
example).

Drop all notion of "points" from the file-format definition of our font
size.

I'm inclined remove this option:

; postscript-font-scale real
;
; Sets a scaling factor for the text in the PostScript output.  This
; can be used to make the output postscript font slightly larger to
; more closely match the text in the printout to the size of the text
; on the screen.
;  The default value is 1.0.
(postscript-font-scale 1.0)


Screen and print _must_ match, and that means fixing this at 1.3.
I don't want to add an option to adjust the combined scaling, since this
just gives too many degrees of freedom.
