A demo which results in high memory allocation

This bug reproduces with LBSE on.

There's high memory allocation when rendering a <path> element over a <video> and the SVG view box coordinate space is large. Attached is a demo.

The memory consumption is exacerbated as the view box dimensions and path+video sizes are increased even if the final rendered size is unchanged.
