Implement :auto_fit option for image size calculation.
When the image is larger than the box, the original: fit option does not change the image size. The :auto_fit option changes the image size to fit in the box while maintaining the aspect ratio.
Usage:
image '/path/to/image.png', at: [100, 100], auto_fit: [100, 100]
Calls superclass method
