// Generates a visual grid of elements of type |graphicElemTagName|, with the
// attribute values given in |graphicElemAttrHash|. This is a variation of the
// above function. We use <defs> to include the reference elements because
// some animatable properties are only applicable to some specific elements
// (e.g. feFlood, stop), so then we apply an animation element of type
// |animationTagName|, with the attribute values given in |animationAttrHash|,
// to those specific elements. |defTagNameList| is an array of tag names.
// We will create elements hierarchically according to this array. The first tag
// in |defTagNameList| is the outer-most one in <defs>, and the last tag is the
// inner-most one and it is the target to which the animation element will be
// applied. We visualize the effect of our animation by referencing each
// animated subtree from some graphical element that we generate. The
// |graphicElemIdValueProperty| parameter provides the name of the CSS property
// that we should use to hook up this reference.
//
// e.g. if a caller passes a defTagNameList of [ "linearGradient", "stop" ],
// this function will generate the following subtree:
// <defs>
// <linearGradient id="elem0">
// <stop>
// <animate ..../>
// </stop>
// </linearGradient>
// <linearGradient id="elem1">
// <stop>
// <animate ..../>
// </stop>
// </linearGradient>
//
// <!--- more similar linearGradients here, up to START_TIMES.length -->
// </defs>
