This relands commitcb4d587666which was reverted by commitb6d2be1330because the original CL broke some blink layout tests, and the first reland was reverted by commit because it broke filterfastbounds gm. This reland let SkImageSource::onFilterNodeBounds() return the dst rect with ctm applied when mapping forward or otherwise the default value. Original description: > Previously SkImageSource::filterBounds() uses the default > SkImageFilter::onFilterNodeBounds() which returns the input rect. > > Now override onFilterNodeBounds() in SkImageSource to return src > or dst rect (with transform applied).
