  # Calzini expects "radius" to mean the x-axis-aligned radius, not y-axis-aligned.
  # For an axis-aligned oval the two may be different.

  # If we have no width, but a radius, default the width to be the radius * 2
  @width ||= @radius * 2 if @radius

  # We now know we have width or height, but maybe not both.

  # Default to a circle - set height from width or vice-versa
  @width ||= @height
  @height ||= @width

  # If we don't have radius yet, set it from width
  @radius ||= @width / 2
