* fix culling issue in LayerTree::Flatten
SkPaint does not provide APIs for extracting the definitions of some
attributes such as filters. The engine will instead use DlPaint
to describe how text foregrounds and backgrounds will be painted.
The DlPaint objects will be represented as PaintIDs in SkParagraph text
styles. The ParagraphPainter will then map the PaintIDs back to the
original DlPaint objects.
* [Reland] Add rects to accumulator rather than bounds (#37435)
When the accumulator is an `RTreeBoundsAccumulator` rather than a `RectBoundsAccumulator` just accumulating the bounds results in incorrect results as the `rtree` would need to be aware of the constituent non-overlapping rectangles. This would work fine for `RectBoundsAccumulator` as it would just adjust its bounds based on the passed rects.

* Update display_list_image_filter_unittests to be permit Skia roll
https://skia-review.googlesource.com/c/skia/+/571798 had to be reverted because it causes DisplayListImageFilter.LocalImageFilterBounds to fail. With SkMatrixTransformImageFilter (returned by SkImageFilters::MatrixTransform) supporting complex matrices, makeWithLocalMatrix(rotation) will no longer return null.
This is at odds with the behavior of DlImageFilter's implementation which tries to mimic the existing behavior of image filters. This relaxes the test case so that Skia can improve its implementation without breaking Flutter's tests. Flutter can then update DlImageFilter to match out-of-band.
* Update comment to reference flutter issue.
* Revert "Fix a clang-tidy warning in display_list_canvas_unittests.cc (#37062)"
This reverts commit 709c6735fc7ed34df36cee23805bdaa7f6969774.
* Revert "Create a mechanism to manage layer state (#36458)"
This reverts commit 501916deb19a8303ca2a3a9bb37692a873d4679e.
