When image filters are processed within Skia, they simply do
a blind recursion. This has the side-effect of turning the
DAG into a tree. I.e., nodes visited more than once during
the traversal will be processed more than once.

This change implements a very simple cacheing scheme: a
cache is created before traversing the DAG, and handed
into the processing traversal. Before recursing into a child
in SkImageFilter::filterImage(), the cache is checked for a
hit, and early-out is performed. Otherwise, the node is
processed, and its result bitmap and location (offset) are
cached, but only if it contains two or more children and
thus will be visited again during the traversal.

Currently, the child count is approximated with the
refcount. This is good enough in most cases (and exactly
correct for the Chrome use case). We could add an exact
child count to the image filter, but this will require
violating the immutability of image filters slightly in
order to bump the child count as nodes are connected. I
leave it up to the reviewer to decide which is better.

NOTE: this patch set is based on https://codereview.chromium.org/189913021/,
and needs that patch to land first.

Until now, crop rects in Skia have only been able to reduce
the size of the destination bounds, but not expand them.
SVG semantics require the latter as well. The heart of
the change is in applyCropRect(), which now assigns each
edge, instead of doing an intersection with the crop rect.

In order to support this (and still work well with tiled
drawing) we need to clip the resulting crop rect to the
clipping region of the filters. This uses the Context struct
previously landed from https://codereview.chromium.org/189913021/.

Many of the pixel loops are not yet ready to handle a
destination rect larger than the source rect. So we provide
a convenience version of applyCropRect() which creates an
offscreen and pads it out with transparent black. Once the
pixel loops and shaders have been fixed to support larger
destination bounds, they should be switched back to the
non-drawing version of applyCropRect().

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.

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.

Eliminates SkFlattenable{Read,Write}Buffer, promoting SkOrdered{Read,Write}Buffer
a step each in the hierarchy.

What used to be this:

SkFlattenableWriteBuffer -> SkOrderedWriteBuffer
SkFlattenableReadBuffer -> SkOrderedReadBuffer
SkFlattenableReadBuffer -> SkValidatingReadBuffer

is now

SkWriteBuffer
SkReadBuffer -> SkValidatingReadBuffer

Benefits:
- code is simpler, names are less wordy
- the generic SkFlattenableFooBuffer code in SkPaint was incorrect; removed
- write buffers are completely devirtualized, important for record speed

This refactoring was mostly mechanical. You aren't going to find anything
interesting in files with less than 10 lines changed.

I had resisted this (and may later put in an assert that the CTM contains no rotation, skew or perspective), but it just makes the filters play better with Skia generally.

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.

This is required by SVG semantics, and is more sane anyway.

To do this, this patch changes the "offset/loc" parameter in filterImage() / onFilterImage() from an inout-param to an out-param only, so that the calling filter can know how much the input filter wants its result offset (and doesn't include the original primitive position). This offset can then be applied to the current filter's crop rect. (I've renamed the parameter "offset" in all cases to make this clear.) This makes the call sites in SkCanvas/SkGpuDevice responsible for applying the resulting offset to the primitive's position, which is actually a fairly small change.

This change also fixes SkTileImageFilter and SkOffsetImageFilter to correctly handle an input offset, which they weren't before. This required modifying the GM's, since they assumed the broken behaviour.

NOTE: this will require rebaselining the imagefiltersgraph test, since it has a new test case.

NOTE: this will "break" the Blink layout tests css3/filters/effect-reference-subregion-chained-hw.html and css3/filters/effect-reference-subregion-hw.html, but it actually makes them give correct results. It should be suppressed on the skia roll, and I'll rebaseline it.

2 ) If a device fails to allocate its pixels, the device will be deleted and NULL will be returned to avoid attempting to draw on a bad device.
