# Convert a node representation to text
# in some different forms
# o output to an object with an interface subset of Tk Text
# o output to ascii-only - best attempt w.o. different fonts
# o output to man-page text
# Parameterized on out
# I have to define the roles of responsibility.
# out is a thin layer above something Tk text-like
# it isolates some details but doesn't provide real new functionality
# Node2Inter takes care of the general formatting
# It needs to know about
# o the size of out, i.e. width and height
# o the fonts and sizes available
# o the special characters available
# o the size of the fonts
# o we restrict to fixed size fonts
# otherwise it would have to ask for size of strings?
#
# to be able to do
# o line wrapping
# o paragraphs
# o headers
# o item and bullet lists
# o tables
# The out can 'record' its commands
# and play them on an actual Tk text window.
# with a simple translation
# o it can operate stack-free
# -- so after eg a font change, there is a font change back
# Does the out has a configuration table
# such as,
# o the fonts to choose
# o for different sizes
# o whether to make items bold
# In any case there may be default here..
