 				Creates a handle material with its variants (selected and/or editable) and adds them to the internal material list. They can then be accessed with [method get_material] and used in [method EditorNode3DGizmo.add_handles]. Should not be overridden.
+				You can optionally provide a texture to use instead of the default icon.
