    <thetext>The system comes to a crawl when SVG images are hovered over. There is clearly an inefficiency here.

The issue may be that we are copying Cairo&apos;s path data each time we inspect it due to a limitation/our misuse of the Cairo path API.</thetext>

    <thetext>I was looking for a good way to reproduce this. Is going to http://www.croczilla.com/svg/samples/chem1/chem1.svg, hovering the mouse over the circles, and measuring CPU usage a good metric?</thetext>
