The anchor sets the origin point of the sprite. The default value is taken from the {@link PIXI.Texture|Texture} and passed to the constructor.
The default is (0,0), this means the sprite's origin is the top left.
Setting the anchor to (0.5,0.5) means the sprite's origin is centered.
Setting the anchor to (1,1) would mean the sprite's origin point will be the bottom right corner.
If you pass only single parameter, it will set both x and y to the same value as shown in the example below.

Current transform of the object based on local factors: position, scale, other stuff.
Sets a mask for the displayObject. A mask is an object that limits the visibility of an
object to the shape of the mask applied to it. In PixiJS a regular mask must be a
{@link PIXI.Graphics} or a {@link PIXI.Sprite} object. This allows for much faster masking in canvas as it
utilities shape clipping. To remove a mask, set this property to null.
For sprite mask both alpha and red channel are used. Black mask is the same as transparent mask.

If true PixiJS will Math.floor() x/y values when rendering, stopping pixel interpolation. Advantages can include sharper image quality (like text) and faster rendering on canvas. The main disadvantage is movement of objects may appear less smooth. To set the global default, change {@link PIXI.settings.ROUND_PIXELS}

Return an array listing the events for which the emitter has registered listeners.
Calculates and returns the (world) bounds of the display object as a [Rectangle]{@link PIXI.Rectangle}.
This method is expensive on containers with a large subtree (like the stage). This is because the bounds
of a container depend on its children's bounds, which recursively causes all bounds in the subtree to
be recalculated. The upside, however, is that calling getBounds once on a container will indeed update
the bounds of all children (the whole subtree, in fact). This side effect should be exploited by using
displayObject._bounds.getRectangle() when traversing through all the bounds in a scene graph. Otherwise,
calling getBounds on each object in a subtree will cause the total cost to increase quadratically as
its height increases.
The _bounds object stores the last calculation of the bounds. You can use to entirely skip bounds
calculation if needed.
const lastCalculatedBounds = displayObject._bounds.getRectangle(optionalRect);
Do know that usage of getLocalBounds can corrupt the _bounds of children (the whole subtree, actually). This
is a known issue that has not been solved. See [getLocalBounds]{@link PIXI.DisplayObject#getLocalBounds} for more
details.
getBounds should be called with skipUpdate equal to true in a render() call. This is because the transforms
are guaranteed to be update-to-date. In fact, recalculating inside a render() call may cause corruption in certain
cases.

Renders the object using the WebGL renderer.
The [_render]{@link PIXI.Container#_render} method is be overriden for rendering the contents of the
container itself. This render method will invoke it, and also invoke the render methods of all
children afterward.
If renderable or visible is false or if worldAlpha is not positive, this implementation will entirely
skip rendering. See {@link PIXI.DisplayObject} for choosing between renderable or visible. Generally,
setting alpha to zero is not recommended for purely skipping rendering.
When your scene becomes large (especially when it is larger than can be viewed in a single screen), it is advised to employ culling to automatically skip rendering objects outside of the current screen. The @pixi-essentials/cull and pixi-cull packages do this out of the box.
The [renderAdvanced]{@link PIXI.Container#renderAdvanced} method is internally used when when masking or filtering is applied on a container. This does, however, break batching and can affect performance when masking and filtering is applied extensively throughout the scene graph.
