css - SVG 微笑 : animateTransform replace to set(opacity and scale attributes)

Question

我可以用 animateTransform raplace 来设置吗？

<animateTransform attributeName="transform" attributeType="XML" type="scale" from="1" to="1.15" repeatCount="1" begin="mousedown+0.2s" dur="0.2s" fill="freeze"></animateTransform>
<animateTransform attributeName="transform" attributeType="XML" type="scale" from="1.15" to="1" repeatCount="1" begin="mouseup+0.4s" dur="0.2s" fill="freeze"></animateTransform>

对于 transform(scale) 的操作，就像我在此处使用“stroke-opacity”属性所做的那样:

<rect x="-0.5" y="-0.5" width="1" height="1" fill="white">
  <set attributeName="stroke-opacity" begin="mouseover" end="mouseout" to="0.5"></set>
  <set attributeName="stroke-opacity" begin="mouseout" end="mouseover" to="1"></set>
</rect>

我试着得到这样的东西

<rect x="-0.5" y="-0.5" width="1" height="1" fill="white">
      <set attributeName="transform" type="scale" begin="mousedown" end="mouseout" to="1.15"></set>
      <set attributeName="transform" type="scale" begin="mouseup" end="mouseover" to="1"></set>
</rect>

但是这个结构不起作用。

有效:

Example of hover(using set): http://jsfiddle.net/exn2qr0s/

Example of click (using animateTransform): http://jsfiddle.net/exn2qr0s/1/

它不起作用:

Example of click (using set): http://jsfiddle.net/exn2qr0s/2/

我需要使用 set 标签而不是 animateTransform 来创建放大效果，当“鼠标按下”导致 animateTransform 在上次 Fire Fox 更新后现在工作不正常时(Deprecated SMIL SVG animation replaced with CSS or Web animations effects (hover, click))

根据 table in the SVG specification animateTransform 仅适用于变换和所有其他动画元素，包括 <set>不处理转换。
