Breaking compatibility: If a StateMachineTransition is connected to a nested StateMachine prior to this, it is removed. Also, there was a feature to connect another StateMachine as the End of a StateMachine, which is also removed to avoid reference confusion. It was like a GoTo Statement, also further passing the same reference to the blending process, causing the blending calculation to break or causing some StateMachines to not work.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Allows specifying an expression as a condition for state machine transitions.
This gives much greater flexibility for creating complex state machines. By directly interfacing with the script code, it is possible to create complex animation advance condition for switching between states.
Ensure assigning AnimationTreeStateMachineTransition base expression node in editor is relative to current AnimationTree node.
Allow setting an expression base node on the AnimationTree itself.

* Map is unnecessary and inefficient in almost every case.
* Replaced by the new HashMap.
* Renamed Map to RBMap and Set to RBSet for cases that still make sense
(order matters) but use is discouraged.
There were very few cases where replacing by HashMap was undesired because
keeping the key order was intended.
I tried to keep those (as RBMap) as much as possible, but might have missed
some. Review appreciated!
- Open the menu to add new animation nodes by dragging the transitions to
empty areas and automatically connecting them.
- Adds box selection to the state machine.
- Add feature to group/ungroup selected nodes in a "sub" state machine.
- Add start/end node by default. In addition, add new color to these
nodes to differentiate then.
- Add tooltip for transitions to show the connection "from -> to".
- Add new "type" of transition line when multiple transitions are
grouped.
- Add popup to connect nodes in sub state machine.
- Add dialog to select which nodes can be deleted when they are grouped.
- Add classes:
AnimationNodeStartState
AnimationNodeEndState
EditorAnimationMultiTransitionEdit
- Implements disabled transition
API Changes:
- Now it's posible to add transitions between state machines,
`AnimationNodeStateMachine::add_transition` will works with relative path,
this means you can use it like this `add_transition("Idle", "Walk", tr)`
or `add_transition("Idle", "StateMachine/Shoot)`.
* New track type BLEND_SHAPE
* Blend shapes are imported via this new track type
* Processing is more optimized (no longer relies on variants)
* Modified the Blend Shape API in MeshInstance3D to use indices rather than StringNames (more optimizes)
* Promo: Fixed a small bug in gizmo updating in Node3D that affected performance
Dedicated BlendShape tracks are required for both optimization and eventually implementing them in animation compression.
* `Animation.TYPE_TRANSFORM3D` track is gone.
* Added POSITION_3D, ROTATION_3D, SCALE_3D tracks.
* GLTF2, Collada, FBX importers will only import the track types found.
* Skeleton3D bone poses are now Pos/Rot/Scale, pose matrix removed.
* AnimationPlayer and AnimationTree animate these tracks separately, only when found.
* Removed BakeReset code, is useless with these changes.
This is the first in a series of commits designed to make the animation system in Godot more useful, which includes:
* Better compatibility with Autodesk products
* Better reusability of animations across models (including retargeting).
* Proper animation compression.
* etc.
*Note* GLTF2 animation saving went broken with this PR, needs to be fixed in a subsequent one.
