 	Base class of anything 2D. Canvas items are laid out in a tree and children inherit and extend the transform of their parent. CanvasItem is extended by [Control], for anything GUI related, and by [Node2D] for anything 2D engine related.
-	Any CanvasItem can draw. For this, the "update" function must be called, then NOTIFICATION_DRAW will be received on idle time to request redraw. Because of this, canvas items don't need to be redraw on every frame, improving the performance significan'tly. Several functions for drawing on the CanvasItem are provided (see draw_* functions). They can only be used inside the notification, signal or _draw() overrides function, though.

 	Canvas items are draw in tree order. By default, children are on top of their parents so a root CanvasItem will be drawn behind everything (this can be changed per item though).
 	Canvas items can also be hidden (hiding also their subtree). They provide many means for changing standard parameters such as opacity (for it and the subtree) and self opacity, 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.

 	Input device events ([InputEvent]) are first sent to the root controls via the [method Node._input], which distribute it through the tree, then delivers them to the adequate one (under cursor or keyboard focus based) by calling [method MainLoop._input_event]. There is no need to enable input processing on controls to receive such events. To ensure that no one else will receive the event (not even [method Node._unhandled_input]), the control can accept it by calling [method accept_event].
 	Only one control can hold the keyboard focus (receiving keyboard events), for that the control must define the focus mode with [method set_focus_mode]. Focus is lost when another control gains it, or the current focus owner is hidden.
 	It is sometimes desired for a control to ignore mouse/pointer events. This is often the case when placing other controls on top of a button, in such cases. Calling [method set_ignore_mouse] enables this function.
-	Finally, controls are skinned according to a [Theme]. Setting a [Theme] on a control will propagate all the skinning down the tree. Optionally, skinning can be overrided per each control by calling the add_*_override functions, or from the editor.

+	Static body for 2D Physics. A static body is a simple body that is not intended to move. They don't consume any CPU resources in contrast to a [RigidBody2D] so they are great for scenario collision.
 	A static body can also be animated by using simulated motion mode. This is useful for implementing functionalities such as moving platforms. When this mode is active the body can be animated and automatically computes linear and angular velocity to apply in that frame and to influence other bodies.
 	Alternatively, a constant linear or angular velocity can be set for the static body, so even if it doesn't move, it affects other bodies as if it was moving (this is useful for simulating conveyor belts or conveyor wheels).
