Skia is beginning to refactor its SkImageFilter codebase. As part of this, we are providing a new set of API factory functions that are accessible from a single header.

engine/lib/ui/painting/image_filter.cc should be updated to use the factory functions exposed in third_party/skia/include/effects/SkImageFilters.h, instead of having to include each image filter's header. Then should be able to replace:

• SkPictureImageFilter::Make(picture->picture()) with SkImageFilters::Picture(picture->picture())
• SkBlurImageFilter::Make(sigma_x, sigma_y, nullptr, nullptr, SkBlurImageFilter::kClamp_TileMode) with SkImageFilters::Blur(sigma_x, sigma_y, SkTileMode::kClamp, nullptr)
• SkImageFilter::MakeMatrixFilter(ToSkMatrix(matrix4), static_cast<SkFilterQuality>(filterQuality), nullptr) with SkImageFilters::MatrixTransform(ToSkMatrix(matrix4), static_cast<SkFilterQuality>(filterQuality), nullptr)
