/**
Base class of anything 2D.

Canvas items are laid out in a tree; children inherit and extend their parent's transform. $(D CanvasItem) is extended by $(D Control) for anything GUI-related, and by $(D Node2D) for anything related to the 2D engine.
Any $(D CanvasItem) can draw. For this, $(D update) must be called, then $(D 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 $(D CanvasItem) are provided (see `draw_*` functions). However, they can only be used inside the $(D GodotObject._notification), signal or $(D _draw) virtual functions.
Canvas items are drawn in tree order. By default, children are on top of their parents so a root $(D CanvasItem) will be drawn behind everything. This behavior can be changed on a per-item basis.
A $(D 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:) Unless otherwise specified, all methods that have angle parameters must have angles specified as $(I radians). To convert degrees to radians, use $(D @GDScript.deg2rad).
