Bug 1383650 - Optimize attribute mapping by not parsing same thing twice r=longsonr Geometry properties are the most used SVG attributes. When authors specify them as attributes, we have to parse them in SVG side. So we don't want to parse them in CSS side again, otherwise the introduced performance loss is relatively high. With this optimization, this feature implementation doesn't slow down overall performace even if there are thousands of geometry elements.
