Re: Animation in selfmade front end

This is, by far, the easiest solution for developers to implement... at
least the bit about getting WMF using Display[].  I don't know enough
about VB to know what the best method of animating WMF's, but you may
get slightly better animation performance if you turn the WMF's into
bitmaps.

If you just happen to have access to some type of PostScript rendering
module, it wouldn't be terribly difficult to turn Mathematica
PostScript into something you could render, but you'd be doing
basically the same thing that Display[] does for you.
