76d4d04b18 Refactor SkMorphologyImageFilter, CPU and GPU paths. This required making opts/ dependent on effects/, so that we could use the SkMorphologyProc type in SkMorphologyImageFilter.h. 
Correctness and performance covered by existing tests; no change in functionality.

a612d4c513 Implement a resize image filter. This is needed for the "filterRes" feature in SVG filter effects, which specifies the required size for intermediate processing buffers. 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.

d494b09f55 Align SkLumaColorFilter with the spec. 
The spec requires the resulting RGB channels for LuminanceToAlpha to be
0 (and not just scaled by the luminance value</facepalm>):

  | R' |     |      0        0        0  0  0 |   | R |
  | G' |     |      0        0        0  0  0 |   | G |

  | A' |     | 0.2125   0.7154   0.0721  0  0 |   | A |
  | 1  |     |      0        0        0  0  1 |   | 1 |

(http://www.w3.org/TR/2011/REC-SVG11-20110816/filters.html#feColorMatrixElement)

This doesn't affect luminance masking (which depends only on the
resulting alpha channel), but other color filter users may care
about all color components.

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 is a patch by Andrei Parvu <parvu@adobe.com> (Adobe CLA signer).

Original CL/review: https://codereview.chromium.org/24078006/

GM:lumamode will need rebaselining after landing this.

---

  In order to use CSS luminance masking, we need to be able to create an
  instance of SkLumaXfermode which can receive a kSrcOver mode, and applies
  that mode after converting the source using the luminance-to-alpha
  coefficients.

4b681bc95b Fixed issues found by fuzzer 
Last week, the fuzzer found a few numerical issue with filters and I had written some fixes for them. Here are the fixes with some unit tests.

For senorblanco : So I figured out what was asserting when we'd get a 0 width "result" in SkBicubicImageFilter::onFilterImage(). Basically, if the "result" SkBitmap object calls SkBitmap::setConfig() with "width" and/or "height" set to 0, then the SkBitmap object will call SkBitmap::reset(), making the SkBitmap object's config invalid. At this point, calling SkBitmap::getAddr32() will assert, even without attempting to dereference the data pointer, because the SkBitmap's config is invalid. If height is valid, but width is 0, then this call to SkBitmap::getAddr32() happens directly in SkBicubicImageFilter::onFilterImage() a few lines lower and asserts right away.

fbaea53366 In image filters, apply the CTM and offset to the crop rect. This is necessary to compensate for both clipping applied by the compositor (communicated via the CTM) and for cropping applied in upstream image filters (communicated via the offset). This requires a few ugly conversions, since the crop rect is an SkIRect, and the ctm is an SkMatrix. 
I also had to offset the matrix passed to filter evaluation by drawSprite() and internalDrawBitmap() by the primitive position. This is the same offset that is applied when drawing the primitive, to compensate for the internal saveLayer().

Also apply the total matrix to the filter params in asNewEffect(), so that (for example) lighting params are offset by both the compositor clipping and upstream crop rects.

4e16bb2a32 Implement crop rect for lighting image filters. Changes for the CPU path were fairly straightforward: use the bounds rectangle when traversing the pixels, not the source rectangle. 
For the GPU path, this required modifying the signature of SkImageFilter::asNewEffect() to receive the bounds offset, so that the lighting filters could offset the light position by the offset. It also required modifying the base-class implementation of SkImageFilter::filterImageGPU() (which implements single-pass filters) to intersect against the bounds rect, to pass its offset to asNewEffect(), and to modify the caller's offset (so it's drawn in the correct place).

Note: this will require rebaselining the lighting GM. Six new test cases were added, to accommodate a cropped version of each lighting filter.

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.

7b320703d4 Implement offset for GPU filter path. Although we can't yet use this in Blink for FEOffset, due to SVG semantics, we can use it to support crop rect (upcoming patch). 
This patch adds the parameter to the filterImageGPU() signature, plumbs through the code on the GPU side, and implements support for it in SkXfermodeImageFilter for both raster and GPU.

Of the remaining filters with GPU implementations, Blur, Morphology, Bicubic and Displacement work fine; they're commutative wrt offset and can simply pass it up the chain. Blend is not, but will be removed shortly anyway (has been replaced with SkXfermodeImageFilter in Blink).

86fc266eda Implement SkXfermode image filter. This required changing the signature of SkXfermode::asNewEffectOrCoeffs(), to add an optional background texture. 
For the raster path, we do a straightforward 2-pass method: draw background, then composite the foreground over it.

For the GPU path, if the xfermode can be expressed as an effect, we build an effect with the background texture incorporated, then do a single-pass draw fetching both foreground and background textures, and compositing to the result. If the xfermode is expressed as src/dst coefficients, we do a 2-pass draw as in the raster path and use fixed-function blending.

Doing it this way required modifying the arithmode GM to use saveLayer()/restore() rather than creating an offscreen SkBitmap, since otherwise the compositing is always done in raster mode. Fixing that in turn exposed that SkArithmeticMode did not work in Picture mode, since it wasn't flattenable. Made it so.

d043ccee37 Allow single-pass filters (which use asNewEffect()) to participate in the image filter DAG. This was done by introducing the SkSinglePassImageFilter abstract base class, which implements canFilterImageGPU() and filterImageGPU() on behalf of the derived class. The derived class still only needs to asNewEffect(). This allows us to recurse on the filter input in SkSinglePassImageFilter::onFilterImageGPU(). It also allows us to remove any knowledge of single-pass image filters from SkGpuDevice and from the SkImageFilter base class as well.

a1c511b870 New SkRectShaderImageFilter image filter 
This new changelist also introduces a new image filter called SkRectShaderImageFilter which is make to simply apply a shader on a region without using any inputs.

TEST=Added ShaderImageFilter test

ba3a3c93b2 revert name changes to SkBlendImageFilter. It (correctly) named its enum kMultiply_Mode, 
and handled that itself internally, rather than calling SkXfermode. This CL removes
the kModulate_Mode alias from its list.

c2594f4106 This changes the signature of SkImageFilter::filterImageGPU() to use SkBitmaps for input and output, and removes the rect param. This allows us to return textures which are larger than the actual result, such as when GrAutoScratchTextures are used. The SkBitmap's size represents the active region, while the GrTexture's size is the full texture size. 
This fixes the bicubic image filter GM on the GPU, which otherwise draws garbage outside the filtered region.  It also moves us closer to unifying the signatures of SkImageFilter::onFilterImage() and SkImageFilter::filterImageGPU().

3f2d45aff6 (Relanding r7275 with assert fix, plus fixes from r7276, r7280, r7283.) 
Implement a bicubic resampling image filter, with raster and GPU backends.
In order to get this to work on the GPU side, I had to modify the width and height of the drawn texture in drawSprite() and drawDevice() to use the filtered texture's dimensions, instead of the source texture.  (This wasn't a problem before since all other image filters produce results the same dimensions as their input texture.)
For now, this implementation only does axis-aligned scaling (same as the Lanczos-3 implementation in Chrome).  It's also done for correctness and clarity, not speed, so there are lots of opportunities for speedups.

171f5c76b9 Rename onFilterImageGPU to filterImageGPU(), to match skia convention. No change in functionality. 
(Note that this does mean that clients must override onFilterImage() to implement the raster path, but filterImageGPU() to implement the GPU path.)
