Using the Desmos API to add an image

Here's a hack for adding images to Desmos:

{
    type: "image",
    id: "1",
    image_url: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAgAAAAIAQMAAAD+wSzIAAAABlBMVEX///+/v7+jQ3Y5AAAADklEQVQI12P4AIX8EAgALgAD/aNpbtEAAAAASUVORK5CYII',
    name: 'whatever',
    x:"3",
    y: "5",
    angle: "4",
    width: "20",
    height: "5",
    opacity: "0.1"
}

Description of each parameter:

image_url
A base64 encoded image. I've only tried PNG, so other image formats might work too.
name
Just some label given to the image. Doesn't really matter.
x
The center \(x\)-position.
y
The center \(y\)-position.
angle
Rotation of the image, counterclockwise, in radians.
width
Width of the image in Desmos units.
height
Height of the image in Desmos units.
opacity
1 = fully visible, 0 = fully transparent
