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
PIXI.Graphics or a 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.

The zIndex of the displayObject.
If a container has the sortableChildren property set to true, children will be automatically sorted by zIndex value; a higher value will mean it will be moved towards the end of the array, and thus rendered on top of other display objects within the same container.

Recalculates the content bounds of this object. This should be overriden to calculate the bounds of this specific object (not including children).

Adds one or more children to the container.
Multiple items can be added like so: myContainer.addChild(thingOne, thingTwo, thingThree)
The DisplayObject(s) to add to the container
The first child that was added.
Adds a child to the container at a specified index. If the index is out of bounds an error will be thrown
The child to add
The index to place the child in
The child that was added.
Recalculates the bounds of the container.
This implementation will automatically fit the children's bounds into the calculation. Each child's bounds is limited to its mask's bounds or filterArea, if any is applied.
Removes all internal references and listeners as well as removes children from the display list.
Do not use a Container after calling destroy.
Pair method for enableTempParent
Actual parent of element
Calls each of the listeners registered for a given event.
Used in Renderer, cacheAsBitmap and other places where you call an updateTransform on root
const cacheParent = elem.enableTempParent();
elem.updateTransform();
elem.disableTempParent(cacheParent);
current parent
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.
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.

Calling getLocalBounds may invalidate the _bounds of the whole subtree below. If using it inside a render()
call, it is advised to call getBounds() immediately after to recalculate the world bounds of the subtree.

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 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.

Container is a general-purpose display object that holds children. It also adds built-in support for advanced rendering features like masking and filtering.
It is the base class of all display objects that act as a container for other objects, including Graphics and Sprite.
