c5d9bb0f67 Initial picture shader implementation
This CL adds an SkPictureShader class to support SkPicture-based
patterns.

The implementation renders the picture into an SkBitmap tile and then
delegates to SkBitmapProcShader for the actual operation.

Reason for revert:
breaking the buildbots. Subsequent CL only addressed CompareGMs but GenerateGMs are also failing.

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.)

Fix GPU displacement with expanding crop rects, and re-enable the
imagefilterscropexpand GM. There were two bugs: the result texture was
being created at input color bitmap size, not the cropped bounds size,
and the matrix in GrContext was not being set to identity before draw.

118252962f Implement support for expanding crop rects in image filters
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().

d4d44f08d7 Re-enable imageresizetiled, but skip it in tilegrid and rtree.
This change makes kSkipTiled_Flag also skip --tileGrid and --rtree.
All GMs which were passing kSkipTiled_Flag before were also passing
kSkipPicture_Flag, which also skips tilegrid and rtree, so this should
have no effect on them, but provides a smaller hammer for GMs which
still want to test picture playback, but not tiling.

The exception is magnifier, which was passing only kSkipTiled_Flag,
but magnifier is an odd beast and not web-exposed, so I'm not worried
about reducing its coverage slightly.

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.

2bfe36b68d Apply the CTM to filter parameters for SkBlurImageFilter, SkDropShadowImageFilter, SkDisplacementMapEffect and SkMorphologyImageFilter. 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.

In order to make this work, we need to render the primitive at the given resolution (doable at the callsite in Blink), and then to resize the result to the actual on-screen size. The latter is where this filter comes in.
It simply applies a scaling factor (and the current CTM) to its input, and draws its input bitmap at that size.

e93e1dbf0e Implement srcRect and dstRect functionality in SkBitmapSource. This is required for the "preserveAspectRatio" options of SVG's feImage. Covered by new GM "bitmapsource".
This also includes some changes to the xfermodeimagefilter and tileimagefilter GMs to properly handle the CTM. This worked before only because SkBitmapSource was ignoring the CTM. Now that it respects it, we need to give the correct transform. This also means the GMs now work while zoomed. It also implements CTM support for SkTileImageFilter.

NOTE: this will require rebaselining a number of imagefilter GMs on Nexus4, since they render in perspective (using the CTM). The changes to the results should all be improvements.

af35920e6d Implement srcRect and dstRect functionality in SkBitmapSource. This is required for the "preserveAspectRatio" options of SVG's feImage. Covered by new GM "bitmapsource".
Note: I initially implemented this as a fully-generic SkResizeImageFilter, but then I realized that the dstRect should always be transformed by the filter matrix, but that the srcRect should not (since it's specified relative to the dimensions of the original bitmap). Since this would be confusing for someone attempting to use this as a generic resizing filter, I decided to build the functionality into SkBitmapSource instead.

1a4fb70c8a Moving 4 SkImageFilter derived classes from blink to skia
There were 4 classes in blink that derived from SkImageFilter :
- TileImageFilter -> SkTileImageFilter
- OffsetImageFilter -> SkOffsetImageFilter (already existed)
- FloodImageFilter -> SkFloodImageFilter
- CompositeImageFilter -> SkCompositeImageFilter

All functions were copied as is, without modification (except for warnings fixes), except for the offset filter, which was merged into the existing SkOffsetImageFilter class, as a special case when a crop rect is provided. Since the names won't clash with the names in blink, it should be easy to integrate them in blink later and fix issues, if needed.

This reverts commit 16a6c9d28c8ef6f827d50ef258005fa5ec971bd9.

Seems to be breaking all of the windows debug bots in GM.

194d775edc This patch implements a crop rect for SkImageFilter. It has been implemented for SkColorFilterImageFilter and SkBlurImageFilter as examples.
In order to preserve the immutability of SkImageFilters, the crop rect is passed as a constructor parameter. If NULL (the default), the bounds of the input image are used, as before.

This also tightens up the boundary handling for SkImageBlurFilter on the GPU backend. Where we were previously using clamping semantics, we now respect decal semantics (so we don't oversaturate the edges). This brings the GPU and raster backends into closer alignment, but will require some new baselines for the GPU tests.

At a minimum, the following tests will need new baselines: imageblur, imagefiltersbase, imagefilterscropped, spritebitmap.

d64d8a905a Working plumb of image scaling:
1) always generate mipmaps if we detect that we are downsampling.
2) pre-scale the image if we detect that we are upsampling
   (currently valid for scale+translate only)
3) A few miscellaneous bug fixes related to image scaling.

Still need SSE/Neon versions of these image scalers.
