commit-bot@chromium.org 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).

SkBlurMaskFilter.h Modify the blur bench to add tests for high-quality blurs, and large non-integer blurs. Change the Coarse flag (which just turns on separable blurs) to an #ifdef, since separable is no longer just Coarse. (This #ifdef will hopefully be shortlived, once Chrome has switched). 2012-11-29 17:09:27 +00:00

SkLightingImageFilter.h Nuke SkSingleInputImageFilter. 99% of its functionality was refactored into SkImageFilterUtils in https://code.google.com/p/skia/source/detail?r=7467, so it has outlived its usefulness. 2013-02-04 22:57:21 +00:00
SkMagnifierImageFilter.h 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. 2013-04-08 19:43:22 +00:00
