Removes a node from the [param group]. Does nothing if the node is not in the [param group]. See notes in the description, and the group methods in [SceneTree].

<return type="void" />
<param index="0" name="new_parent" type="Node" />
<param index="1" name="keep_global_transform" type="bool" default="true" />
<description>
Changes the parent of this [Node] to the [param new_parent]. The node needs to already have a parent.
If [param keep_global_transform] is [code]true[/code], the node's global transform will be preserved if supported. [Node2D], [Node3D] and [Control] support this argument (but [Control] keeps only position).
