This is great news Duncan!

If you do consider adding support for movie15, the Asymptote graphics
language may be handy:

http://asymptote.sourceforge.net/

Asymptote can embed 3D graphs into LaTeX documents that are fully
zoomable/manipulatable. It also uses LaTeX to typeset the figure text.

Thanks.  That doesn't look easy, but it would indeed be a nice addition.
