The img element is used for bitmap images in 99% of all cases. The rendering of
bitmap images is very fast.

When using the img element with svg documents as source, the rendering is
slower because WebKit repaints the SVG every time the img is painted.

An obvious optimization is to cache the rendered SVG and update the cache as
the SVG contents changes.
