	<brief_description>
		A [SkeletonModifier3D] that apply transform to the bone which copied from reference.
	</brief_description>
	<description>
		Apply the copied transform of the bone set by [method BoneConstraint3D.set_reference_bone] to the bone set by [method BoneConstraint3D.set_apply_bone] with processing it with some masks and options.
		There are 4 ways to apply the transform, depending on the combination of [method set_relative] and [method set_additive].
		[b]Relative + Additive:[/b]
		- Extract reference pose relative to the rest and add it to the apply bone's pose.
		[b]Relative + Not Additive:[/b]
		- Extract reference pose relative to the rest and add it to the apply bone's rest.
		[b]Not Relative + Additive:[/b]
		- Extract reference pose absolutely and add it to the apply bone's pose.
		[b]Not Relative + Not Additive:[/b]
		- Extract reference pose absolutely and the apply bone's pose is replaced with it.
		[b]Note:[/b] Relative option is available only in the case [method BoneConstraint3D.get_reference_type] is [constant BoneConstraint3D.REFERENCE_TYPE_BONE]. See also [enum BoneConstraint3D.ReferenceType].

				Sets additive option in the setting at [param index] to [param enabled]. This mainly affects the process of applying transform to the [method BoneConstraint3D.set_apply_bone].
				If sets [param enabled] to [code]true[/code], the processed transform is added to the pose of the current apply bone.
				If sets [param enabled] to [code]false[/code], the pose of the current apply bone is replaced with the processed transform. However, if set [method set_relative] to [code]true[/code], the transform is relative to rest.

				Sets the flags to process the transform operations. If the flag is valid, the transform operation is processed.

			<description>
				Sets the flags to inverte axes. If the flag is valid, the axis is copied.
				[b]Note:[/b] An inverted scale means an inverse number, not a negative scale. For example, inverting [code]2.0[/code] means [code]0.5[/code].
				[b]Note:[/b] An inverted rotation flips the elements of the quaternion. For example, a two-axis inversion will flip the roll of each axis, and a three-axis inversion will flip the final orientation. However, be aware that flipping only one axis may cause unintended rotation by the unflipped axes, due to the characteristics of the quaternion.

				If sets [param enabled] to [code]true[/code], the extracted and applying transform is relative to the rest.
