     This test verifies that fePointLight stays in the right place when the user

     zooms the page.

     If the test passes, you should see a green box with its center illuminated

     by a point light. If the test fails, the illumination will be off-center.

     This test checks that SVG filters transform points in user space to points

     in filter space correctly.

     The root SVG element specifies a width and height to prevent scrollbars

     from appearing when the page is zoomed.
