<!-- Test CSS clip and shadow with composited layers. Left and right sides
     should have the same shape. In old code where this caused a bug,
     crbug.com/246728, shadows cause a slightly different code path than
     clip.html without shadow. In this test, the clip is still larger than the
     shadow's extent; The composited layer should not clamp to the shadow's
     extent (1 pixel), it should include the full extent of the clip as well (5
     pixels). -->
