- Added support for explicitly specifying the transitions trigger time when using state machine automatic transition rules.
- Fixed state machine automatic transitions rules not triggering from a looping animation.
- Fixed state machine automatic transitions rules that have their next state as a conduit state triggering before reaching the end of the animation.
- Consolidate all the ways to check if asset in asset player is looping into a single api call, IsLooping().
- Added getter for a AssetPlayer's DeltaTimeRecord.
- Added warning when a asset player is using looping animations with automatic rule based transitions.

Per-node constant data is now held on a generated struct as part of sparse class data.
Per-node mutable data (i.e. pin links/property access mappings) is now held on a generated 'mutable data' struct that is compiled as part of the generated class.
The anim BP compiler is now extended more conventionally using UAnimBlueprintExtension, derived from UBlueprintExtension. This directly replaces the older 'compiler handler' pattern that was added in an emergency fashion for 4.26. Anim graph nodes now request their required extensions and these are held on the UAnimBlueprint in the UBlueprint::Extensions array. The Extensions array is potentially refreshed with any node addition or removal. The Extensions array is force-refreshed each time an anim BP is compiled for the first time to deal with newly added or removed requirements.
Const-corrected a bunch of UAnimInstance/FAnimInstanceProxy APIs that rely on (now truly) const data.
Added a split state/constant version of FInputScaleBiasClamp to allow some of its data to be split into constants.
Tweaked alignment/ordering of FPoseLinkBase to save a few bytes per pose link.
Deprecated FAnimNode_Base::OverrideAsset in favor of a more UAnimGraphNode_Base-based approach. Individual nodes can still have runtime overrides via specific accessors. The new approach will also give us the oppurtunity to override multiple assets per node if required in the future.
Moved property access into Engine module & removed event support from it - this was never used.
Reworked property access compilation API a little - construction/lifetime was a bit confusing previously.
Optimized path used to create UK2Node_StructMemberSet nodes in per-node custom events. When using mutable data, the structure used is large and very sparsely connected (i.e. only a few properties are written) so we only create pins that are actually going to be used, rather than creating all of them and conly connecting a few.
Patched the following nodes to use the new data approach:
- Asset players (sequences, blendspaces, aim offsets)
- Blend lists
- Ref poses
- Roots

[CL 16071104 by Thomas Sarkanen in ue5-main branch]
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.

Improved blend profile support adding a time based method.

[CL 14831887 by john vanderburg in ue5-main branch]
Users can now select the blend profile mode: Blend Weight Factor based or Time Factor based.
The Blend Weight Factor method is the legacy method, which multiplies the transition blend weight with the per bone factor.
The new Time Factor method allows you to specify a time factor. A value of 0.5 would mean the bone would take half the time of the transition to reach its target state, while a value of 0.1 would mean it takes a tenth of the time, etc. A value of 0 would make the bone instantly transition into the target state.

Removed direct access to currently compiling BP class to restrict unguarded mutation.
Const-corrected various accessors and overrides.
Moved UObject-based compiler subsystems to 'handlers' and removed UObject dependency.
Moved from set of virtual functions on subsystems/handlers to a restricted set of contexts passed to specific multicast delegates that handlers subscribe to.
Removed anim class subsystems.
Moved property access code to engine module (editor code is still in a plugin).
Fixed nativized builds where anim BPs have nativized/non-nativized classes in the hierarchy
