I didn't think so, because after mptopdf got hold of the figure, the
whitespace around the figure was right and mptopdf should have used the
bbox in the figure. So my only guess was that the internal conversion
to pdf was getting confused somewhere.

My hypothesis was refuted by testing the rectangle. I had hoped (if
that's the right word) that the internal conversion was using the width
where it should have used the height, which is why the ellipse would
cause problems. Which is why I tried the square, and it was fine --
more evidence for the theory. But the rectangle was fine, so my theory
died.

That fixes it here, thanks. I see what happened with my test cases now.
The ellipse had its lower left corner away from the origin, so the old
analyzedfigureheight was larger than it should have been. But the
rectangle and square start at the origin, so you don't see the effect.

Good to know. Plus I was wondering how to do that anyway.
