[PD] pd font finetuning with tk scaling ?

[Miller Puckette]

Well, the "courier" font on Windows is much taller for the same width than
on Linux or Mac.  I think most of the difference isn't the height of the
characters but the empty space between lines.

Tuesday mornings are difficult for me -- office hours and teaching.

cheers
