## Ellipses

- `((draw-ellipse viewport) posn width height color)`
  Takes a viewport descriptor. It returns a function that draws an ellipse border in the viewport. The posn, width, and height arguments are as in `draw-rectangle`; the ellipse is inscribed within the specified rectangle. The optional color argument defaults to black.
- `((clear-ellipse viewport) posn width height)`
  Takes a viewport descriptor. It returns a function that clears an ellipse border in the viewport. The posn, width, and height arguments are as in `clear-rectangle`; the ellipse is inscribed within the specified rectangle. The optional color argument defaults to black.
- `((flip-ellipse viewport) posn width height color)`
  Takes a viewport descriptor. It returns a function that flips an ellipse border in the viewport. The posn, width, and height arguments are as in `flip-rectangle`; the ellipse is inscribed within the specified rectangle. The optional color argument defaults to black.
- `((draw-solid-ellipse viewport) posn width height color)`
  Takes a viewport descriptor. It returns a function that paints a solid ellipse in the viewport. The posn, width, and height arguments are as in `draw-rectangle`; the ellipse is inscribed within the specified rectangle. The optional color argument defaults to black.
- `((clear-solid-ellipse viewport) posn width height)`
  Takes a viewport descriptor. It returns a function that erases a solid ellipse in the viewport. The posn, width, and height arguments are as in `clear-rectangle`; the ellispse is be inscribed within the specified rectangle. The optional color argument defaults to black.
- `((flip-solid-ellipse viewport) posn width height color)`
  Takes a viewport descriptor. It returns a function that flips a solid ellipse in the viewport. The posn, width, and height arguments are as in `flip-rectangle`; the ellipse is be inscribed within the specified rectangle. The optional color argument defaults to black.
