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