Rebaseline tests affected by Skia r13323.

The above Skia change altered the semantics of filters slightly, in that
offscreen buffers used for blurs and drop shadows are no longer
clipped to the clipping region (although the resulting drawing still
is).  This matches the behaviour of Firefox and IE10.

See https://code.google.com/p/skia/source/detail?r=13323.
