0a5c233e3b Implement bounds traversals for tile and matrix convolution filters. 
Add a new GM that exercises tiled drawing all pixel-moving filters
(and some non-pixel-moving ones) and compares it against non-tiled
drawing of the same filters. Fixing this test revealed that tile and
matrix convolution filters had no onFilterBounds() traversals
(test-driven development FTW). Tile requires (conservatively) the
bounds to include the whole source rect, since it may end up in the
result. Matrix convolution requires the bounds to be offset by the
kernel size and target.

As a first step towards removing SkShader::setLocalMatrix, which will make
SkShader thread-safe, remove calls to setLocalMatrix that happen immediately
after the shader is being created. Instead, pass the matrix into the constructor
or factory method.

ee845ae494 Fix SkXfermodeImageFilter when an input is cropped out. 
If one of inputs to SkXfermodeImageFilter draws nothing, either due to
it being cropped out upstream, or within the filter itself, the filter
should still draw the other input, since otherwise the result will be incorrect.

For the GPU path, since we can't detect this case in
canFilterImageGPU() without recursing, we'll just drop to
the generic path if either input is empty, since we can't use the effect in that case anyway.

While we're at it, let's drop to the generic path if the
xfermode can't be expressed as an effect, since the code
here was doing a 2-pass render in that case anyway, which
is equivalent to what the (xfermode == NULL) case was doing
anyway.

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.)

4cb543d605 Implement support for a Context parameter in image filters 
Some upcoming work (support for expanding crop rects) requires
the clip bounds to be available during filter traversal. This change
replaces the SkMatrix parameter in the onFilterImage() traversals
with a Context parameter. It contains the CTM, as well as the clip
bounds.

SkDrawLooper carries some state during draws. This CL extracts this state into
a separate class Context, which is then passed by the users of SkDrawLooper
into the appropriate methods.
This is a step towards making SkDrawLooper immutable.

fd5c9a6e04 Begin making SkPerlinNoiseShader const. 
The overall goal is to make SkShader itself immutable (BUG=skia:1976).
The fields cannot yet be made constant, due to the constructor which
takes an SkReadBuffer. Other than that constructor, the fields are now
unchanged.

Remove setTileSize and initPaint. Merge initPaint with the constructor
of PaintingData, since it is only ever used on a new PaintingData.
Merge setTileSize with the SkPerlinNoiseShader constructor, its only
call site.

48f31bdbb3 try to deprecate fFlagsMask from SkLayerDrawLooper 
We think we want to move around how flags/fields like linearText and strikeThru
are specified. SkPaint has helpers for nearly all of these, but LayerInfo in
the draw looper just exposes the raw bitfield.

On survey of chrome/android, it appears that no one uses those, so it may be
safe to just remove the feature entirely from the looper.

SkResizeImageFilter resizes all the pixels from its input (subject to

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.

74ba2f62dc Builder class for SkLayerDrawLooper. 
SkLayerDrawLooper provides methods like addLayer() to build up a linked list
of layers. Working towards making this class immutable, this patch introduces
the SkLayerDrawLooperBuilder class which is used to accumulate all the layers
first. Once all layers are in place, it creates a new SkLayerDrawLooper object
and hands over the list of layers to that object.

For now we keep the addLayer methods in SkLayerDrawLooper so we don't break
Chrome and Blink when this is landed. Once we've updated all users, we can
remove the methods.

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.

8b0e8ac5f5 Refactor read and write buffers. 
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.

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.

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.

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.

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.

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.

The separable blur algorithm gives +45% on SampleBlur, +84% on SampleBigBlur, +31% on TheVerge, +35 to +85% on blurbench in HQ (depending on size), +8 to +35% in low quality.  (All of these on 32bit MacPro).

Existing filters which maintained their own filter connectivity were refactored to use the new constructors and flattening/unflattening code.  Modifying the remaining filters which are not yet DAG-friendly is left for future work; they are considered to have zero inputs for now.

3bc16c8bc1 Implement GPU path for matrix convolution. Note that when not convolving alpha, 
the premultiplying is done less efficiently than in the raster path:  it's
done on each texture access, rather than as a pre-processing pass.   This was
so I could do the filter as a single custom stage; will try the optimization
separately.

This implementation gives a ~30X speedup on the GPU results for the
matrixconvolution bench (~10X due to the GPU, and ~3X due to texture
uploads/readback removal).

Note:  this changes the matrixconvolution for the software path as well, so
it will likely break the bots until that test is rebaselined.

f1369ce607 Implements a new class, SkSingleInputImageFilter, to handle DAG connectivity 
for filters with a single image input.  This provides functionality to store,
flatten and unflatten a single SkImageFilter input, as well as to recursively
evaluate it on the CPU or GPU.  The following classes were re-parented to 
implement DAG connectivity:  SkBlurImageFilter, SkDilateImageFilter,
SkErodeImageFilter, SkColorFilterImageFilter.  The constructors for each
have been appended with a new parameter, representing the input filter
(default NULL).

This change also implements an arbitrary SkBitmap input source for filtering,
SkBitmapSource.

NOTE:  This CL will require gyp file changes when rolling past this revision.

c73dd5c688 Update SkFlattenable buffers to be more modular. 
This CL is an effort to stage the conversion to named
parameters for all SkFlattenable commands. This particular
stage only does the following two things...

1. Move flattenable buffers from SkFlattenable.h into
   their own header.
2. Update and Add new read write methods for better clarity
   and convenience.

302cffba86 Replace the asAFoo() functions in SkImageFilter with canFilterImageGPU() and 
onFilterImageGPU() virtuals.  This allows each filter to implement its own GPU
processing code, even for multi-pass filters.

894790d77c This patch implements the diffuse and specular lighting filters in Ganesh. 
There are three light types for each:  distant, point and spot, whose code
generation lives in a GrGLLight class hierarchy.  This similar to the CPU
implementation, where each light type provides a function to compute the vector
from the surface plane to the light (surfaceToLight) and to compute the light
colour (emitLightColour).  Instead of templated member functions, as in the CPU
implementation, these are virtual functions to emit the light-specific GLSL
code.

All of the code for the GPU path lives in the same file as that for the CPU
path, SkLightingImageFilter.cpp.  In order to provide Ganesh a hook to access
it, SkImageFilter now has a asNewCustomStage() virtual, which allows an image
filter to return a GrCustomStage representing that filter.

Note that this patch does not handle the border conditions correctly (the
[top|bottom][Left|Right]Normal() functions in the CPU implementation).  That
will come in a future patch.

bdb1ec453a Minor cleanup in lighting image filters: Made the light color a member of the 
light, rather than the filter, so computation is localized.  Changed a couple
of non-const refs in the image filter creation API const refs.  Changed "const
SkColor&" to "SkColor", since it's just a uint32_t anyway.

f49b429cef Raster implementation of diffuse and specular lighting filters. Externally, 
the caller instantiates a light (distant, point or spot), and an
SkDiffuseLightingFilter or SkSpecularLightingImageFilter with that light.  A
Sobel edge detection filter is applied to the alpha of the incoming bitmap, and
the result is used as a height map for lighting calculations.
