Yes, we have access to a single wire carrying the signal current (I remember
enough of my 27-year old EE degree to catch that).
But I had my doubts about a current transformer, because of the chance of
having several bits at the same level, either high or low current, not giving
any signal;
I had a quick look at the routine and must say that I did not grasp the code.
It is probably due to some heavy optimizations.
My approach had been more in the line of:
// Assumption done on ArcType in that the StartAngle attribute is the
// arcs CCW rotation with zero meaning that attribute

Heavy optimizations, perhap, but also because it is wrong.

According to the manual ( I just checked) Arc is just a quarter
circle even though it is overspecified in terms of parameters.
Ellipses are not mentioned.
Technically, what we have is *not* an ellipse - it's a stretched arc.

The linear stretching transformation (x', y') = (a*x, b*y) applied to a
circle yields an ellipse whose axes are parallel to the coordinate axes.

The linear stretching transformation (x', y') = (a*x, b*y) applied
to a circle yields an ellipse whose axes are parallel to the
coordinate axes.
Yes, *unless* you're including the start/end angles in that
transformation, instead of applying them afterwards.

And there is no way to specify a slanted ellipse in the file format
either, so if we really want ellipses, the file format is incomplete
and should be changed.
