Implement built-in classes Vector4, Vector4i and Projection.
* Two versions of Vector4 (float and integer).
* A Projection class, which is a 4x4 matrix specialized in projection types.
These types have been requested for a long time, but given they were very corner case they were not added before.
Because in Godot 4, reimplementing parts of the rendering engine is now possible, access to these types (heavily used by the rendering code) becomes a necessity.
**Q**: Why Projection and not Matrix4?
**A**: Godot does not use Matrix2, Matrix3, Matrix4x3, etc. naming convention because, within the engine, these types always have a *purpose*. As such, Godot names them: Transform2D, Transform3D or Basis. In this case, this 4x4 matrix is _always_ used as a _Projection_, hence the naming.
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.

Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)
In AnimationTree::_process_graph, the State.valid variable is set to true.
A few lines later, it's set again. Probably a copy/paste mistake. This
commit removes the second assignment.
Remove warning about animations in different libraries having the same name, since shared names are fine.
Also fix missing vformat argument when setting the name of an animation to one that does conflict with an animation in the same library.
* Replace case-by-case extraction with PNAME & GNAME
* Fix group handling when group hint begins with property name
* Exclude properties that are PROPERTY_USAGE_NO_EDITOR
* Extract missing ADD_ARRAY*, ADD_SUBGROUP* macros
- Fix a bug causing an error message when a scene containing an AnimationPlayer with a reset track is saved, by correctly referencing the temporary "default" library.
- Make library dropdown in new animation window assign correct library when creating an animation.
- Similarly allow choice of library when duplicating animation.
- Make library dropdown default to library of currently selected animation.
- Make library dropdown show when exactly one library exists, and it isn't [Global]. Include [Global] on the dropdown in this case (will be newly created if dialog is confirmed).
- When appending (x) to avoid New Anim name collisions, correctly check target library instead of [Global].
- Add parentheses when appending x when duplicating animations in the library editor, for consistency.
- Change titles and prompts to be distinct in name/rename/duplicate dialiogs.
- Fix bug in OprionButton.get_selectable_item(true) when last is not selectable.
- Fix issues where animation wasn't found on deletion/rename by correctly prepending library name.
- Remove an extraneous print_line from animation_track_editor.
- Add messages to errors when an animation isn't found.
* 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!
Adds a new, cleaned up, HashMap implementation.
* Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing).
* Keeps elements in a double linked list for simpler, ordered, iteration.
* Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much
for performance vs keeping the key, but helps replace old code).
* Uses a more modern C++ iterator API, deprecates the old one.
* Supports custom allocator (in case there is a wish to use a paged one).
This class aims to unify all the associative template usage and replace it by this one:
* Map<> (whereas key order does not matter, which is 99% of cases)
* HashMap<>
* OrderedHashMap<>
* OAHashMap<>
These typedefs don't save much typing compared to the full `Ref<Resource>`
and `Ref<RefCounted>`, yet they sometimes introduce confusion among
new contributors.
- 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)`.
