Yes, I have discussed about that with Richard Koch, and he plans to
leave the original mpost engine as it is, not to break anything. The
“mptopdf” engine should be replaced by nv-metafun instead.

Nice, I hadn't realized that. Could you please send me an example that I

nv-metapost can be instructed not to output PDF if you don't want
(there's a FAQ entry in the README about that). The engine nv-metapost
with PDF output turned off just runs mpost, as the current mpost engine
in TeXShop does.

I do not agree. The old 'mptopdf' in TeXShop runs mptopdf, so it is able
to process MetaFun macros and deal with specials like externalfigure,
transparency, etc... My nv-metafun does that, but nv-metapost doesn't
(at least, not by default).
