"""Creates ImageGraphic from an image file.
Scales image to match the `size` aspect ratio.
Arguments:
`image_path`: pathlib.Path object
Denotes the path to the image.
`center_offset`: Vector2
The position of the center of the image relative to the
`location` of the ImageGraphic
`size`: Vector2
The dimensions of the image
Returns:
