	</brief_description>
	<description>
		Base class of anything 2D. Canvas items are laid out in a tree; children inherit and extend their parent's transform. [CanvasItem] is extended by [Control] for anything GUI-related, and by [Node2D] for anything related to the 2D engine.
		Any [CanvasItem] can draw. For this, [method queue_redraw] is called by the engine, then [constant NOTIFICATION_DRAW] will be received on idle time to request redraw. Because of this, canvas items don't need to be redrawn on every frame, improving the performance significantly. Several functions for drawing on the [CanvasItem] are provided (see [code]draw_*[/code] functions). However, they can only be used inside [method _draw], its corresponding [method Object._notification] or methods connected to the [signal draw] signal.
		Canvas items are drawn in tree order. By default, children are on top of their parents so a root [CanvasItem] will be drawn behind everything. This behavior can be changed on a per-item basis.
		A [CanvasItem] can also be hidden, which will also hide its children. It provides many ways to change parameters such as modulation (for itself and its children) and self modulation (only for itself), as well as its blend mode.
		Ultimately, a transform notification can be requested, which will notify the node that its global position changed in case the parent tree changed.
		[b]Note:[/b] Unless otherwise specified, all methods that have angle parameters must have angles specified as [i]radians[/i]. To convert degrees to radians, use [method @GlobalScope.deg_to_rad].

	<methods>
		<method name="_draw" qualifiers="virtual">
			<return type="void" />
			<description>
				Called when [CanvasItem] has been requested to redraw (after [method queue_redraw] is called, either manually or by the engine).
				Corresponds to the [constant NOTIFICATION_DRAW] notification in [method Object._notification].

		<method name="draw_animation_slice">
			<return type="void" />
			<param index="0" name="animation_length" type="float" />

			<return type="Rect2" />
			<description>
				Returns the viewport's boundaries as a [Rect2].
			</description>
		</method>
		<method name="get_viewport_transform" qualifiers="const">
			<return type="Transform2D" />
			<description>
				Returns this item's transform in relation to the viewport.
			</description>
		</method>
		<method name="get_world_2d" qualifiers="const">
			<return type="World2D" />
			<description>
				Returns the [World2D] where this item is in.
			</description>
		</method>
		<method name="hide">
			<return type="void" />
			<description>
				Hide the [CanvasItem] if it's currently visible. This is equivalent to setting [member visible] to [code]false[/code].
			</description>
		</method>
		<method name="is_local_transform_notification_enabled" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if local transform notifications are communicated to children.
			</description>
		</method>
		<method name="is_transform_notification_enabled" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if global transform notifications are communicated to children.
			</description>
		</method>
		<method name="is_visible_in_tree" qualifiers="const">
			<return type="bool" />
			<description>
				Returns [code]true[/code] if the node is present in the [SceneTree], its [member visible] property is [code]true[/code] and all its antecedents are also visible. If any antecedent is hidden, this node will not be visible in the scene tree, and is consequently not drawn (see [method _draw]).
			</description>
		</method>
		<method name="make_canvas_position_local" qualifiers="const">
			<return type="Vector2" />
			<param index="0" name="screen_point" type="Vector2" />
			<description>
				Assigns [param screen_point] as this node's new local transform.
			</description>
		</method>
		<method name="make_input_local" qualifiers="const">
			<return type="InputEvent" />
			<param index="0" name="event" type="InputEvent" />
			<description>
				Transformations issued by [param event]'s inputs are applied in local space instead of global space.
			</description>
		</method>
		<method name="move_to_front">
			<return type="void" />
			<description>
				Moves this node to display on top of its siblings. This has more use in [Control], as [Node2D] can be ordered with [member Node2D.z_index].
				Internally, the node is moved to the bottom of parent's children list. The method has no effect on nodes without a parent.
			</description>
		</method>
		<method name="queue_redraw">
			<return type="void" />
			<description>
				Queues the [CanvasItem] to redraw. During idle time, if [CanvasItem] is visible, [constant NOTIFICATION_DRAW] is sent and [method _draw] is called. This only occurs [b]once[/b] per frame, even if this method has been called multiple times.
			</description>
		</method>
		<method name="set_notify_local_transform">
			<return type="void" />
			<param index="0" name="enable" type="bool" />
			<description>
				If [param enable] is [code]true[/code], this node will receive [constant NOTIFICATION_LOCAL_TRANSFORM_CHANGED] when its local transform changes.
			</description>
		</method>
		<method name="set_notify_transform">
			<return type="void" />
			<param index="0" name="enable" type="bool" />
			<description>
				If [param enable] is [code]true[/code], this node will receive [constant NOTIFICATION_TRANSFORM_CHANGED] when its global transform changes.
			</description>
		</method>
		<method name="show">
			<return type="void" />
			<description>
				Show the [CanvasItem] if it's currently hidden. This is equivalent to setting [member visible] to [code]true[/code]. For controls that inherit [Popup], the correct way to make them visible is to call one of the multiple [code]popup*()[/code] functions instead.

			The texture filter blends between the nearest 4 pixels and between the nearest 2 mipmaps. Use this for non-pixel art textures that may be viewed at a low scale (e.g. due to [Camera2D] zoom), as mipmaps are important to smooth out pixels that are smaller than on-screen pixels.
