This reverts commit 35ac48c715.
Reason for revert: guarded needs_subset
Original change's description:
> Revert "Fill intermediate device image with clamped backdrop content"
>
> This reverts commit 25f5e1f838.
>
> Reason for revert: needs_subset is unused for no-gpu+release builds
>
> Original change's description:
> > Fill intermediate device image with clamped backdrop content
> >
> > Adds asShader() to SkSpecialImage that accepts a local matrix and a
> > tilemode. It automatically handles the subsetting of the image data
> > (either by making a new bitmap view, or using GrTexturEffect), as well
> > as modifying the local matrix to account for the subset's offset within
> > the image data.
> >
> > By adding asShader(), SkCanvas can fill a device using drawPaint() to
> > apply the image's tilemode to the entire contents, ensuring that any
> > device bounds clipping from snapping of backdrop filters doesn't leave
> > the default transparent pixels around for later filtering.
> >
> > Additionally, making SkSpecialImage more like a shader will make it
> > easier down the road to continue refactoring the image filter pipeline
> > to be more backend agnostic and allow operations to be performed by
> > filling devices with shaders, instead of relying on FPs directly.
> >
> > Lastly, once SkImage::makeShader() can support subsets on the raster
> > backend, then SkSpecialImage may not be required at all in order to
> > implement the image filtering pipeline...
