Surely. In fact I'd already done that. I was just wondering why . . . and
also noting that if done, it would gain me access to the X resource menuFont
if the font had never been set. In case anyone needs to fiddle with fonts
in windows, hopefully the following offering will avoid their having to
reinvent that wheel. Thanks for the response. --Jim

# font.py: simple font manager. Jim Densmore, DSA Colorado Springs, 17-Sep-1994
# Functions:
# current() - return current font
# set(font) - change current font to arg, return whether success
# push(font) - store current font on stack, then return set(font)
# pop() - return to the previously stored font, return success
# default() - same as set(<default font>)
# default(Fn,Args)- return function value with font temporarily defaulted
# reset() - clears stack and does default()
# Warnings:
# 1. If you do "import font" it is easy to accidently later use a local
# variable named "font" and hose the connection to the module.
# 2. I don't know how to make sure the default font is set to same value as
# the X resource "menuFont", so I just assume it is font "fixed". If
# this is a problem and you don't know how to fix it, just push your own
# font onto the stack early. If you do know how to fix it, please send
# me mail at "densmore@dsai.com".
# Globals used:
# _FontManager_default - default font, currently hardwired to "fixed"
# _FontManager_current - current font
# _FontManager_stack - list used as stack of fonts
