+ Attribute structures to UAnimDataModel
* These are sampled/copied into AnimSequence whenever they change
+ Attribute related Notifies and Payloads
+ Controller API and Actions for Attribute related behaviour
+ Type traits (TAttributeTypeTraitsBase) to determine support functionality for user-defined attribute types
+ TAttributeContainer equivalent to TCustomAttributes, used for keeping track of attributes at runtime in a TMap similar fashion
* Has two exported specializations FStack/Heap-AttributeContainer
+ IAttributeBlendOperator interface used for Attribute related operations in Anim graph
* Allows for user-defined blending behaviour for their associated types
+ TAttributeBlendOperator providing out-of-the-box blending behaviour for user-defined types
+ FAttributeBlendData helper structure, this encapsulates and abstracts the blend / attribute operations
* Exposes two iterators, allowing BlendOperator to loop through (type) overlapping Attributes and unique attributes
+ Float/Integer/String Animation Attribute structures used to support legacy TVariant CustomAttribute data types
+ Transform animation attribute structure to add support for single-FTransform based attributes
+ FAnimationAttributeIdentifier identifier used to reference an attribute in a script-friendly manor
+ AttributeTypes static API for registering Attribute types
+ FAttributeCurve providing a curve-type with an Attribute type as its underlying key-value
+ TWrappedAttribute helper structure to wrap end template operate on raw memory (TArray buffer)
+ Added tests for
* Attribute related controller functionality and actions
* Attribute curve key reduction
* Evaluating attributes from AnimSequence
* Attribute operations (blend, accumulate etc)
* Functional testing for blendspace attribute evaluation and blending
* Changed default attribute blend type to Blend vs Override
* Updated FBX import/export paths to handle and use new Attribute data structures
* Attribute data is now incorporated into animation source data DDC key
* Deprecated Custom Attributes stored on AnimSequence get converted into their equivalent Attribute structures
* Deprecated all previous CustomAttribute structures, APIs and files
* Corrected some comments in UAnimDataController.h
* Updated existing custom attribute tests to adhere to new blend expectations/behaviour
* Updated AnimSequence resize tests to also incorporate an attribute curve
* Changed layered bone blend to use .5 blend weight vs 1.0 to cover more behaviour
* Added transform attribute used to compare against bone transform during pre-existing functional testing (blended only)
- Deleted CustomAttributes details customization

Added a new animation graph node that hosts its own UBlendSpaceBase. Modified UBlendSpaceBase to allow for pose links to be evaluated as the sample points.
The new blend space graphs can be spawned from existing UBlendSpace and UBlendSpace1D assets, or they can be created from scratch, or they can be converted from existing blendspace player nodes via the context menu.
Fixed anim node conversion functions so that their transactions work correctly.
Updated FBlueprintEditorUtils::IsGraphNameUnique to allow it to work with any object as the outer, not just UBlueprint. UBlueprint still has a special case for functions and events. This is to support GenerateUniqueGraphName within a scope (e.g. an outer graph).
Formalized the concept of 'node sub-graphs' (as well as the composite node pattern a little). Previously a number of known node types that contained sub-graphs (e.g. UK2Node_Composite) had special case logic for dealing with node/graph deletion etc. Now any node can opt into this behaviour via the GetSubGraphs() override.
Added status bar readouts for the blendspace grid, so we dont have to stuff the prompts into the tooltip any more.
Moved anim BP related APIs out of FBlueprintEditor. They are always used via FAnimationBlueprintEditor.
Refactored graph title bar widget creation out into a function to allow other document tab factories to create it.
Altered breadcrumb trail click callbacks and SMyBlueprint::ExecuteAction to always JumpToHyperLink rather than calling OpenDocument directly. This allows unknown (to FBlueprintEditor) document types that reference objects to be correctly jumped to using the breadcrumb trail. Derived asset editors (i.e. FAnimationBlueprintEditor) can intercept the JumpToHyperlink call to ensure that the correct document is presented (i.e. the correct tab payload is generated).
Instead of making yet another bunch of duplicated code for handling the various alpha blend options, refactored this into FAnimGraphNodeAlphaOptions (for editor code) and FAnimNodeAlphaOptions (for runtime code).
Added OnCopyTermDefaultsToDefaultObject for per-node copying of default values from editor node to runtime node, rather than another special-case in the compiler.

Refactored tick record sync into utility structure - FAnimSync. This improves the odd API around tick records, better encapsulating functionality and leaving less for the caller to get wrong. This will also eventually allow this to be refactored out into a scriptable pipeline stage.
Added sync node and scoped sync message for new 'graph based sync'. Nodes that subscribe to graph-based-sync determine their sync group based on the scope that they are in.
Removed 4.26-style sync scopes - pushed all syncing up to the main anim instance. Linked anim instances no longer sync their own tick records.
To make graph based sync more useful, surfaced graph attributes and their visualizations as labels on pins and parallel wires to visualize flow.
This involves statically determining the attribute flow of the graph at compile time. Added a new compiler handler to deal with this new debug data.
Updated a lot of nodes to specify their attributes so graph flow can be correctly visualized.
Added tracing of attributes and sync records and visualization of traced records when debugging the anim graph.
