		Canvas drawing layer.
	</brief_description>
	<description>
		Canvas drawing layer. [CanvasItem] nodes that are direct or indirect children of a [CanvasLayer] will be drawn in that layer. The layer is a numeric index that defines the draw order. The default 2D scene renders with index 0, so a [CanvasLayer] with index -1 will be drawn below, and one with index 1 will be drawn above. This is very useful for HUDs (in layer 1+ or above), or backgrounds (in layer -1 or below).

	<members>
		<member name="custom_viewport" type="Node" setter="set_custom_viewport" getter="get_custom_viewport">
			The custom [Viewport] node assigned to the [CanvasLayer]. If [code]null[/code], uses the default viewport instead.
		</member>
		<member name="follow_viewport_enable" type="bool" setter="set_follow_viewport" getter="is_following_viewport" default="false">
			Sets the layer to follow the viewport in order to simulate a pseudo 3D effect.
		</member>
		<member name="follow_viewport_scale" type="float" setter="set_follow_viewport_scale" getter="get_follow_viewport_scale" default="1.0">
			Scales the layer when using [member follow_viewport_enable]. Layers moving into the foreground should have increasing scales, while layers moving into the background should have decreasing scales.
		</member>
		<member name="layer" type="int" setter="set_layer" getter="get_layer" default="1">
			Layer index for draw order. Lower values are drawn first.
		</member>
		<member name="offset" type="Vector2" setter="set_offset" getter="get_offset" default="Vector2(0, 0)">
			The layer's base offset.
		</member>
		<member name="rotation" type="float" setter="set_rotation" getter="get_rotation" default="0.0">
			The layer's rotation in radians.
		</member>
		<member name="scale" type="Vector2" setter="set_scale" getter="get_scale" default="Vector2(1, 1)">
			The layer's scale.
		</member>
		<member name="transform" type="Transform2D" setter="set_transform" getter="get_transform" default="Transform2D(1, 0, 0, 1, 0, 0)">
			The layer's transform.
		</member>
		<member name="visible" type="bool" setter="set_visible" getter="is_visible" default="true">
			If [code]false[/code], any [CanvasItem] under this [CanvasLayer] will be hidden.
			Unlike [member CanvasItem.visible], visibility of a [CanvasLayer] isn't propagated to underlying layers.
		</member>

	<signals>
		<signal name="visibility_changed">
			<description>
				Emitted when visibility of the layer is changed. See [member visible].
