[NTG-context] feature request: external figures with XeTeX

Hello Hans, Would it be possible to add high-level support (\externalfigure) for inclusion of external figures in XeTeX? (I didn't know that it worked - I remember a failed experiment from some time ago, but it might have been my fault.) There are two commands: \XeTeXpdffile <filename> <optional options> for PDF (supporting inclusion of different pages) \XeTeXpicfile <filename> <optional options> for "everything else" So for example this should work: \XeTeXpicfile "abc.png" width 8cm (or xscaled 1000 yscaled 2000 for example) (However I don't know which all the available options are.) Thank you, Mojca
