Why not just give a warning if width and height is not equal, saying
that we don't really support ellipses for the moment, and be done with
it.
I could, I suppose, but as you mentioned in another post, there

To do either one analytically looks like a 4th order
equation must be solved. So I am looking for cheap
iterative solutions, or approximations, instead.
If the point is within the arc's bounding box, transform the point's
I am using the polar form of the ellipse given at:

with theta the angle of the point we are checking. (Those cos
and sin calculations are easy, just delta-x/len and delta-y/len.)
With that I can calculate the distance from the
As sort of an extension to heterogeneous symbols I wonder how I can make
generic symbols, consisting of a set of subsymbols, e.g. a relay coil
and several types of contact arrangements like SPST and SPDT, all as
separate, little symbols. In my design I would then select the
appropriate subparts

There is a fairly informative discussion of this problem on SO:

I had a look and found one algebraic solution close to the one I have proposed.
