[NTG-context] cow symbols don't work in MkIV

This works in MkII, but not MkIV. Other symbol sets like mvs work (even with a list of error messages). \starttext \usesymbols[cow] \setupsymbolset[cownormal] \startTEXpage[align={middle,middle},width=210mm,height=297mm] \dontleavehmode\scale[width=\textwidth]{\symbol[CowConTeXt]} Cowboy Coder \stopTEXpage \stoptext Under MkIV I managed to get my hands on the Cows (text) font via \definedfont[Cows at 30mm], but not on CowLogos.
