Fairly obviously, Edita/Arwen uses winAPI, eg from eafonts.ew:

cbid = CallBack(routine_id("EnumFontFamExProc"))
    void = c_func(xEnumFontFamiliesExA,{hDC,lf,cbid,0,0})

It just builds a list of allowed font sizes in EnumFonFamExProc(), which gets
called for each and every permitted facename/pointsize combo.

The only thing I can suggest is that if wxEuphoria is implementing
get_facenames() via:

>>wxFontEnumerator::GetFacenames

Then it might be possible to build valid sizes in a similar fashion via:

>>wxFontEnumerator::EnumerateFacenames

The above quotes are from
http://wxwidgets.org/manuals/stable/wx_wxfontenumerator.html#wxfontenumeratorenumeratefacenames

Not that I properly understand all that  but it would seem to depend on
whether that OnFacename (some kind of virtual function it seems) gets called the
same way or not.
