* Allow UICollectionViewLayout to give us a layout inspector, always call the didChangeDelegate/didChangeDataSource on binding
* Make an assertion
* Update the tests
* Tests use actual layout inspector
* Be more consistent
* Reimplement IGListKit support in a cleaner way
* Rename and fix some stuff
* Fix supplementaries more
* Update docs
* Update test
* Cleanup minor things
* Tweak it
* Indentation
* Remove irrelevant changes
* Break out cell into its own file
* Fix indentation
* Address feedback
* Rejigger our flow layout supplementary support to make more sense.
* Support old protocol
* Update
* Update deprecation message
* Undeprecate insetForSection method, because it actually _does_ still work
* Update the tests
* Remove irrelevant junk
* Remove cast, add pragma
* Start removing ASChangeSetDataController
* Continue removing ASChangeSetDataController
* Remove unnecessary change
* ASDataController is no longer an abstract class, remove its assertion
* Get back beginUpdates and endUpdatesAnimated:completion in ASCollectionNode
* Add tests for baseline alignments
* Merge baseline alignment algorithm to the main stack algorithm
- Baseline alignment is now part of the main stack algorithm.
- ASStackBaselinePositionedLayout is no longer needed and removed.
* All snapshot test cases of ASStackLayoutSpec are passing now
* Remove baselineRelativeArrangement
* Remove TODO
* Minor fixes in cross size determination step
* Test that the initial range bounds are what we expect
* Use the user's previous scroll direction in the range controller
* Remove flow layout assertion
* Improve visibility handling for range-managed nodes
* Tweak ASWeakSet & the test
* Put back a few things that are pending a different diff
* Add a test
* Ensure we update visible nodes, even if there are no new ones
* Fix content insets are wrong in pager node if root node of ASViewController and transition back
* Add unit test
* Improve test
* Fix test
* Move tests to ASPagerNodeTests
* Improve handling of rasterize node interface states and testing
* Fix harder
* Finish fixes and move rasterization flag into beta header
* Re-enable rasterization in ASDKgram
* Re-enable working test
* Only do it in debug
* Fix crash if layout elements are created with no owner and referenced in layoutSpecThatFits:
* Add failing test for nodes deallocated while creating in layoutSpecThatFits:
* Some more
* Some cleanup
* Added more complexity to tests
* Only cache sublayouts if the layout get’s flattened
* Address comments
* Address comments
* Fix flickering for range managed nodes
* Go back to old behavior to check for range managed before calling didExitPreloadState in interface state change
* Replace fetch data with preload terminology
- Deprecate `-fetchData` and `-clearFetchedData` in favor of `-preload` and `-clearPreloadedData`
- Move `-setNeedsPreload`, `-recursivelyPreload` and `-recursivelyClearPreloadedData` to ASDisplayNode+FrameworkPrivate.h
- Update internal implementation, comments and tests
* Folllow up on #2642:
- Remove -preload and -clearPreloadedData in favor of -didEnterPreloadState and -didExitPreloadState.
- -didEnterPreloadState and -didExitPreloadState call the deprecated -fetchData and -clearFetchedData methods if they are overriden.
* Missed one in a test
* Get rid of behavior change for now.
* Revert more behavior changes, fix tests.
* Don't need these anymore.
* Test & tweak batch fetching implementation
* Tighten the test
* Stop batch fetching at the end of range controller pass
* Clean up the test
* Still check for batch fetching after each frame when scrolling
* Ensure batch fetching happens for empty collection/table
Be more aggressive with main thread punting
Trampoline setting the dataSource/delegate onto the main thread
Short-circuit the supplementary nodes method if no data source
Don't rely on assertions
Mark variable unused to fix release builds
Handle ASCollectionNode/ASTableNode deallocation better
Add some comments about new macro
