		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.
		To use [EditorSpatialGizmoPlugin], register it using the [method EditorPlugin.add_spatial_gizmo_plugin] method first.

	<methods>
		<method name="add_material">
			<return type="void" />
			<argument index="0" name="name" type="String" />
			<argument index="1" name="material" type="SpatialMaterial" />
			<description>
				Adds a new material to the internal material list for the plugin. It can then be accessed with [method get_material]. Should not be overridden.
			</description>
		</method>
		<method name="can_be_hidden" qualifiers="virtual">
			<return type="bool" />
			<description>
				Override this method to define whether the gizmos handled by this plugin can be hidden or not. Returns [code]true[/code] if not overridden.
			</description>
		</method>
		<method name="commit_handle" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<argument index="1" name="id" type="int" />
			<argument index="2" name="secondary" type="bool" />
			<argument index="3" name="restore" type="Variant" />
			<argument index="4" name="cancel" type="bool" default="false" />
			<description>
				Override this method to commit a handle being edited (handles must have been previously added by [method EditorSpatialGizmo.add_handles] during [method _redraw]). This usually means creating an [UndoRedo] action for the change, using the current handle value as "do" and the [code]restore[/code] argument as "undo".
				If the [code]cancel[/code] argument is [code]true[/code], the [code]restore[/code] value should be directly set, without any [UndoRedo] action.
				The [code]secondary[/code] argument is [code]true[/code] when the committed handle is secondary (see [method EditorSpatialGizmo.add_handles] for more information).
				Called for this plugin's active gizmos.
			</description>
		</method>
		<method name="commit_subgizmos" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<argument index="1" name="ids" type="PoolIntArray" />
			<argument index="2" name="restore" type="Array" />
			<argument index="3" name="cancel" type="bool" default="false" />
			<description>
				Override this method to commit a group of subgizmos being edited (see [method _subgizmos_intersect_ray] and [method _subgizmos_intersect_frustum]). This usually means creating an [UndoRedo] action for the change, using the current transforms as "do" and the [code]restore[/code] transforms as "undo".
				If the [code]cancel[/code] argument is [code]true[/code], the [code]restore[/code] transforms should be directly set, without any [UndoRedo] action. As with all subgizmo methods, transforms are given in local space respect to the gizmo's Spatial. Called for this plugin's active gizmos.

			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<argument index="1" name="id" type="int" />
			<argument index="2" name="secondary" type="bool" />
			<description>
				Override this method to provide gizmo's handle names. The [code]secondary[/code] argument is [code]true[/code] when the requested handle is secondary (see [method EditorSpatialGizmo.add_handles] for more information). Called for this plugin's active gizmos.
			</description>
		</method>
		<method name="get_handle_value" qualifiers="virtual">
			<return type="Variant" />
			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<argument index="1" name="index" type="int" />
			<argument index="2" name="secondary" type="bool" />
			<description>
				Override this method to return the current value of a handle. This value will be requested at the start of an edit and used as the [code]restore[/code] argument in [method _commit_handle].
				The [code]secondary[/code] argument is [code]true[/code] when the requested handle is secondary (see [method EditorSpatialGizmo.add_handles] for more information).
				Called for this plugin's active gizmos.
			</description>
		</method>
		<method name="get_material">
			<return type="SpatialMaterial" />
			<argument index="0" name="name" type="String" />
			<argument index="1" name="gizmo" type="EditorSpatialGizmo" default="null" />
			<description>
				Gets material from the internal list of materials. If an [EditorSpatialGizmo] is provided, it will try to get the corresponding variant (selected and/or editable).
			</description>
		</method>
		<method name="get_priority" qualifiers="virtual">
			<return type="int" />
			<description>
				Override this method to set the gizmo's priority. Gizmos with higher priority will have precedence when processing inputs like handles or subgizmos selection.
				All built-in editor gizmos return a priority of [code]-1[/code]. If not overridden, this method will return [code]0[/code], which means custom gizmos will automatically get higher priority than built-in gizmos.
			</description>

		<method name="get_subgizmo_transform" qualifiers="virtual">
			<return type="Transform" />
			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<argument index="1" name="id" type="int" />
			<description>
				Override this method to return the current transform of a subgizmo. As with all subgizmo methods, the transform should be in local space respect to the gizmo's Spatial. This transform will be requested at the start of an edit and used in the [code]restore[/code] argument in [method _commit_subgizmos]. Called for this plugin's active gizmos.
			</description>
		</method>
		<method name="has_gizmo" qualifiers="virtual">
			<return type="bool" />
			<argument index="0" name="spatial" type="Spatial" />
			<description>
				Override this method to define which Spatial nodes have a gizmo from this plugin. Whenever a [Spatial] node is added to a scene this method is called, if it returns [code]true[/code] the node gets a generic [EditorSpatialGizmo] assigned and is added to this plugin's list of active gizmos.
			</description>
		</method>
		<method name="is_handle_highlighted" qualifiers="virtual">
			<return type="bool" />

The [code]secondary[/code] argument is [code]true[/code] when the requested handle is secondary (see [method EditorSpatialGizmo.add_handles] for more information). Called for this plugin's active gizmos.
			</description>
		</method>
		<method name="is_selectable_when_hidden" qualifiers="virtual">
			<return type="bool" />
			<description>
				Override this method to define whether a Spatial with this gizmo should be selectable even when the gizmo is hidden.

		</method>
		<method name="redraw" qualifiers="virtual">
			<return type="void" />
			<argument index="0" name="gizmo" type="EditorSpatialGizmo" />
			<description>
				Override this method to add all the gizmo elements whenever a gizmo update is requested. It's common to call [method EditorSpatialGizmo.clear] at the beginning of this method and then add visual elements depending on the node's properties.
			</description>
		</method>
		<method name="set_handle" qualifiers="virtual">
			<return type="void" />
