Could you point me to some of those discussions?  AFAIU, the scaling on
the NS and PGTK ports is generally considered superior to the other
ports, and they simply scale the bitmaps up.

Some of those monitors already default to a 400% scale, so GNOME and NS
already aren't constrained to double scales.

How about using a vector graphics format for the "new" fringe bitmaps?
We already have SVG support, but IMHO SVG is too heavy and isn't present
on every system, so maybe a custom vector graphics format for fringe
bitmaps would be in order.

Thanks.
