		Base class of anything 2D.
	</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 update] must be called, 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 the [method Object._notification], signal or [method _draw] virtual functions.
		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.deg2rad].

If you don't care about this particular use case, usage of this function after submitting the slices is not required.

			<argument index="5" name="pixel_range" type="float" default="4.0" />
			<description>
				Draws a textured rectangle region of the multi-channel signed distance field texture at a given position, optionally modulated by a color. See [method FontData.set_multichannel_signed_distance_field] for more information and caveats about MSDF font rendering.
				If [code]outline[/code] is positive, each alpha channel value of pixel in region is set to maximum value of true distance in the [code]outline[/code] radius.

				[codeblocks]
				[gdscript]
				# If using this method in a script that redraws constantly, move the
				# `default_font` declaration to a member variable assigned in `_ready()`
				# so the Control is only created once.
				var default_font = Control.new().get_font("font")
				var default_font_size = Control.new().get_font_size("font_size")
				draw_string(default_font, Vector2(64, 64), "Hello world", HALIGN_LEFT, -1, font_size)
				[/gdscript]
				[csharp]
				// If using this method in a script that redraws constantly, move the

			The texture filter reads from the nearest pixel, but selects a mipmap based on the angle between the surface and the camera view. This reduces artifacts on surfaces that are almost in line with the camera.
