IIRC, the width and height attributes in HTML just set the corresponding
height and width values in CSS. They don't say anything about the intrinsic
size or aspect ratio. So, for the example given,

    <img src=".." width="100" height="200" style="width: 30%">

would result in following cascaded values:

    width: 30%;
    height: 200px;

not

    width: 30%;
    height: twice the width;
