[NTG-context] "externalfigure" vs. "draw externalfigure" in metafun

Dear Hans, I have problems with externalfigure inside metapost. In MKII, only externalfigure "something.png"; works, while in MKIV only draw externalfigure "something.png"; is accepted. Is there any chance to accept one of the syntaxes in both flavours? Thank you, Mojca Minimal example: \starttext \startMPpage % only good for MKII externalfigure "abc.png" xyscaled (5cm,8cm); % only good for MKIV % draw externalfigure "abc.png" xyscaled (5cm,8cm); \stopMPpage \stoptext
