/facepalm ... this is a pretty obvious regression that I added in SkPictureImageFilter.

This bug also causes the layout test images/color-profile-layer-filter.html to fail.

Ensure SkPictureImageFilter::onFilterImage doesn't double-convert color

Consider the following sequence of events:
1. SkPictureImageFilter::onFilterImage creates a local canvas, wraps it
   in a SkColorSpaceXformCanvas, and passed to...
2. SkPictureImageFilter::drawPictureAtLocalResolution creates a local
   canvas (localCanvas) wraps that in a SkColorSpaceXformCanvas, draws
   the picture to it, doing sRGB->fColorSpace conversion
3. We then call makeImageSnapshot to produce a SkSpecialImage, localImg,
   which is not tagged with any color space.
4. When the draw that localImg to the passed-in SkColorSpaceXformCanvas,
   which then performs sRGB->fColorSpace conversion a second time.

We now have performed color conversion twice.

One fix for this would be to have the image produced by the call to
localSurface->makeImageSnapshot() be tagged with fColorSpace. This is
somewhat involved.

The less invasive fix is to remove the SkColorSpaceXformCanvas in
SkPictureImageFilter::onFilterImage, and push it down into the two
branches, SkPictureImageFilter::drawPictureAtLocalResolution and
SkPictureImageFilter::drawPictureAtDeviceResolution.
