AreaEllipse seems to have a bug. I would get odd lines drawn through my
ellipses. I finally made the problem go away by clearing my area vector
array to zeroes before each call to AreaEllipse.
You should not need AreaMove before an AreaEllipse. You need an AreaEnd
to get the ellipse rendered at the end. (But of course you know this.)
