What is the "fringe font" in this context?  If by that you (Samuel) mean
the size of individual fringe bitmaps, then the reason it cannot scale
is that the code for magnifying fringe bitmaps by the display scale
factor has yet to be written.  PGTK and NS builds are unaffected by this
deficiency because the toolkit assumes responsibility for doing so.

Thanks.
