Ellipse

Description

An ellipse primitive, which is like a circle, but the width and height can be different

Function	Summary
`clone(_self)`	No Documentation 🚧
`eccentricity(_self)`	Returns the [eccentricity](https://en.wikipedia.org/wiki/Eccentricity_(mathematics)) of the ellipse. It can be thought of as a measure of how "stretched" or elongated the ellipse is. The value should be in the range [0, 1), where 0 represents a circle, and 1 represents a parabola.
`eq(_self, other)`	No Documentation 🚧
`focal_length(_self)`	Get the focal length of the ellipse. This corresponds to the distance between one of the foci and t
`from_size(size)`	Create a new `Ellipse` from a given full size. `size.x` is the diameter along the X axis, and `size.y`
`new(half_width, half_height)`	Create a new `Ellipse` from half of its width and height. This corresponds to the two perpendicula
`semi_major(_self)`	Returns the length of the semi-major axis. This corresponds to the longest radius of the ellipse.
`semi_minor(_self)`	Returns the length of the semi-minor axis. This corresponds to the shortest radius of the ellipse.
