8.9. Font-<NSCDE_FONT_DPI>dpi.fvwmgen

... where "DPI" ($NSCDE_FONT_DPI) is by default hardcoded to 96.

This files are regular files in the system-wide configuration, but may be symbolic links to some system wide or local fontset in $FVWM_USERDIR when generated by Font Style Manager.

Font sizes in this config are defined as infostore variables and used across FVWM config files, they are provided to FvwmScript programs with getfont wrapper. Font sizes are in points. While defining them in pixels (pixelsize=) will be easier, and all this care about DPI will not be needed, integration with GTK2 and GTK3 in best of my knowledge and research does not provide a way to define fonts in pixel sizes, so either font sizes in points or unsure recalculation (again based on DPI) will be needed while writing gtk settings.
