Computes the aspect ratio of an image using the HTML width and height attributes so that it can be used for sizing an image using CSS before it loads.
Motivation
To correctly compute the final dimensions of an image (before it is fully loaded), this feature computes the aspect ratio from the HTML width and height attributes, so that it can be used to compute the final size when e.g. "width: 100%; height: auto;" is used in CSS. This avoids unnecessary relayouts when the image loads (compared to <img src="foo.jpg" style="width: 100%">
