Custom gizmo for editing Spatial objects.
</brief_description>
<description>
Custom gizmo that is used for providing custom visualization and editing (handles) for 3D Spatial objects. These are created by [method EditorSpatialGizmoPlugin.create_gizmo].

Used by the editor to define Spatial gizmo types.
</brief_description>
<description>
EditorSpatialGizmoPlugin allows you to define a new type of Gizmo. There are two main ways to do so: extending [EditorSpatialGizmoPlugin] for the simpler gizmos, or creating a new [EditorSpatialGizmo] type. See the tutorial in the documentation for more info.
