 Ah, sorry for misunderstanding you. The wx-dev list is probably the best
place for something like this.

 AFAICS this means reimplementing Windows metafiles in wxWidgets or, at
least, something very similar to it, and this is not easy to do at all and
all but impossible to do efficiently at our level.

 I think we need to keep the idea of having some function called with wxDC
parameter and rendering onto it. But it could be a callback instead of a
virtual function, e.g. a std::function<void (int page, wxDC&)> or something
like this.
