Re: Performance of SVG animation (Mozilla implement)

Sorry, the code is in a  xbl and also an xul, it's hard to make it work in a
standalone envionment.

        <symbol id="common-button-loading-symbol" width="600" height="600"
viewBox="0,0,600,600">
            <line fill="none" stroke="#FFFFFF" stroke-width="40"
stroke-linecap="round" x1="300" y1="90" x2="300" y2="150"/>
            <line opacity="0.80" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="195" y1="118.135" x2="225" y2="
170.096"/>
            <line opacity="0.56" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="118.135" y1="195" x2="170.096"
y2="225"/>
            <line opacity="0.32" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="90" y1="300" x2="150"
y2="300"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="118.135" y1="405" x2="170.096"
y2="375"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="300" y1="450" x2="300"
y2="510"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="375" y1="429.904" x2="405" y2="
481.865"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="429.904" y1="375.001" x2="
481.865" y2="405"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="450.001" y1="300.001" x2="510"
y2="300"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="429.905" y1="225" x2="481.865"
y2="195"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="195" y1="481.865" x2="225" y2="
429.904"/>
            <line opacity="0.20" fill="none" stroke="#FFFFFF"
stroke-width="40" stroke-linecap="round" x1="375.001" y1="170.096" x2="405"

        </symbol>

It's such a symbol that we will rotate it for 30 angle every 300ms. It's
done all by javascript.
