Looking at your patch it can be seen that it is impossible for this algorithm
to draw an ellipse that is an even number of pixels high. You always draw a
certain distance below and above the center and the center is a signed integer,
e.g. it sits directly on a pixel. Thus you always draw an odd number of lines.
