Image filters have never implemented this check, which means that
filters which affect transparent black falsely claim they can compute
their bounds.
Implemented an affectsTransparentBlack() virtual for image
filters, and a similar helper function for color filters.
This will affect the following GMs: imagefiltersscaled
(lighting, perlin noise now filter to clip),
colorfilterimagefilter (new test case), imagefiltersclipped
(perlin noise now filters to clip).
Note: I de-inlined SkPaint::canComputeFastBounds() to avoid adding
a dependency from SkPaint.h to SkImageFilter.h.h. Skia benches show
no impact from this change, but will watch the perf bots carefully.

This fixes every case where virtual and SK_OVERRIDE were on the same line,
which should be the bulk of cases. We'll have to manually clean up the rest
over time unless I level up in regexes.
for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end

This is basically how blink uses the filter. Currently, I can't use it for "ShadowOnly" mode with the filter at all, but instead of copying the code and risking to have the codepaths diverge, I'm simply going to add the option here.

- Rename TileGrid -> Quilt to avoid the name overload.
- Tag all failing GMs with kSkipTiled_Flag.
You may be wondering, do any GMs pass? Yes, some do! And that trends towards all of them as we increase --quiltTile.
Two GMs only fail in --quilt mode in 565. Otherwise all GMs which fail are skipped, and those which don't fail aren't. (The 8888 variants of those two GMs are skipped even though they pass.)

This will be used in Blink to accommodate matrices that contain
rotation or shearing. This is a generalization of SkResizeImageFilter,
so I've replaced all uses of SkResizeImageFilter in Skia. (It might be
easier to review by diffing it with SkResizeImageFilter, too.)

Pass the CTM as part of the local matrix passed by
SkRectShaderImageFilter. Teach SkPerlinNoiseShader to respect the local
matrix. Embiggen imagefiltersscaled GM size to accommodate the new test
cases.
Note: will require rebaselines of imagefiltersscaled and imagefiltersclipped

SkResizeImageFilter resizes all the pixels from its input (subject to
the input's crop rect), but the offset to be applied was incorrect.
It should take the CTM into account, so that the origin of the resize is
the world space origin, unaffected by whatever clipping is applied.
New GM imageresizetiled exercises the behaviour under
impl-side-painting-like conditions, and existing GMs now have resize
cases added.

Image filters in Skia currently clip the size of the the offscreen
bitmap used for filtering to the device clip bounds. This means that
any pixel-moving filter (e.g., blur) has edge artifacts at the clip
boundaries. This is problematic for tiling, where a single SkPicture
is played back with a clip set to the tile boundaries.
By implementing the onFilterBounds() traversal, and using it in
saveLayer() when a filter is present, we can clip the layer to the
expanded clip rect. Note that this requires that the traversal be
performed in reverse as compared to computeFastBounds(). (It's also
done in device space, unlike computeFastBounds()).
New test imagefiltersclipped tests pixel-moving filters when clipped
by various clip rects.
New test imageblurtiled tests tiled (compositor-style) rendering of
blurred text. There should be no artifacts at the tile boundaries.

This revealed that the displacement map was not handling clipping or upstream cropping at all well (the color would "swim" through the displacement at the edge of the clip rect). Fixed by passing through the correct offsets to the bitmap accesses in both raster and GPU paths. Same for morphology.
