Skeleton for 2D characters and animated objects.

Skeleton2D parents a hierarchy of [Bone2D] objects. It is a requirement of [Bone2D]. Skeleton2D holds a reference to the rest pose of its children and acts as a single point of access to its bones.
|
|
To setup different types of inverse kinematics for the given Skeleton2D, a [SkeletonModificationStack2D] should be created. They can be applied by creating the desired number of modifications, which can be done by increasing [member SkeletonModificationStack2D.modification_count].

|
Returns a [Bone2D] from the node hierarchy parented by Skeleton2D. The object to return is identified by the parameter [param idx]. Bones are indexed by descending the node hierarchy from top to bottom, adding the children of each branch before moving to the next sibling.

<description>
|
|
Sets the local pose transform, [param override_pose], for the bone at [param bone_idx].
|
|
[param strength] is the interpolation strength that will be used when applying the pose, and [param persistent] determines if the applied pose will remain.
|
|
[b]Note:[/b] The pose transform needs to be a local transform relative to the [Bone2D] node at [param bone_idx]!
