I tried changing the two arc calls to
.arc(centre = (25, 25), radius = 20, angle1 = -90 * qah.deg, angle2 = 90 * qah.deg, negative = False)
and
.arc(centre = (25, 25), radius = 20, angle1 = 90 * qah.deg, angle2 = 270 * qah.deg, negative = False)
and this made no difference that I could see. So starting and stopping
angles at arbitrary multiples of 90° work just fine.
