I undertook to do this. Lacking experience as a real typographer, I did things by eyeballing them with sample inputs that seemed likely provocative of glyph collisions in mathematical typesetting, and by limiting myself to adjustments in increments of 1/12th em. Here is the result. Really trying to not forget the attachments this time. Regards, Branden
