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.

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.

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.

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.

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().

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.
