234f036b3e Adding an option to render only the shadow in SkDropShadowImageFilter
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.

f539318f0d Cleanup: Get rid of make_isize() function from gm.h.
This helper function is not necessary.

The same thing can be achieved by using SkISize::Make() provided by
SkTSize API.

a90c680386 Turn on quilt mode in DM.
- 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.)

fd0ec2c76a Implement a generic matrix transform image filter.
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.)

cac5fd597f Factory methods for heap-allocated SkImageFilter objects.
This is part of an effort to ensure that all SkPaint effects can only be
allocated on the heap.

This patch makes the constructors of SkImageFilter and its subclasses non-public
and instead provides factory methods for creating these objects on the heap. We
temporarily keep constructor of publicly visible classes public behind a flag.

47d98c8e85 Fix CTM scaling and clipping of SkRectShaderImageFilter.
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

897b73f62c Fix CTM application in SkResizeImagefilter; implement bounds traversals.
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.

c4b12f19a4 Implement correct clipping for image filters.
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.
