In 7.3, GNOME-1.4 just reflects the core X behavior ... as far
as I recall, for scaleable fonts this is determined by the 
'default-resolutions' in /etc/X11/fs/config, for not-scaleable
fonts, by the order of the elements in 'catalogue'.

GNOME in Limbo has an entirely different set of font technologies -
new rasterizer (freetype2), new font system (fontconfig/Xft), new text
layout engine (Pango), so there isn't much commonality.
