/**
* The DisplayObject class is the base class for all objects that can be
* placed on the display list. The display list manages all objects displayed
* in openfl. Use the DisplayObjectContainer class to arrange the
* display objects in the display list. DisplayObjectContainer objects can
* have child display objects, while other display objects, such as Shape and
* TextField objects, are "leaf" nodes that have only parents and siblings, no
* children.
*
* The DisplayObject class supports basic functionality like the _x_
* and _y_ position of an object, as well as more advanced properties of
* the object such as its transformation matrix.
*
* DisplayObject is an abstract base class; therefore, you cannot call
* DisplayObject directly. Invoking `new DisplayObject()` throws an
* `ArgumentError` exception.
*
* All display objects inherit from the DisplayObject class.
*
* The DisplayObject class itself does not include any APIs for rendering
* content onscreen. For that reason, if you want create a custom subclass of
* the DisplayObject class, you will want to extend one of its subclasses that
* do have APIs for rendering content onscreen, such as the Shape, Sprite,
* Bitmap, SimpleButton, TextField, or MovieClip class.
*
* The DisplayObject class contains several broadcast events. Normally, the
* target of any particular event is a specific DisplayObject instance. For
* example, the target of an `added` event is the specific
* DisplayObject instance that was added to the display list. Having a single
* target restricts the placement of event listeners to that target and in
* some cases the target's ancestors on the display list. With broadcast
* events, however, the target is not a specific DisplayObject instance, but
* rather all DisplayObject instances, including those that are not on the
* display list. This means that you can add a listener to any DisplayObject
* instance to listen for broadcast events. In addition to the broadcast
* events listed in the DisplayObject class's Events table, the DisplayObject
* class also inherits two broadcast events from the EventDispatcher class:
* `activate` and `deactivate`.
*
* Some properties previously used in the ActionScript 1.0 and 2.0
* MovieClip, TextField, and Button classes(such as `_alpha`,
* `_height`, `_name`, `_width`,
* `_x`, `_y`, and others) have equivalents in the
* ActionScript 3.0 DisplayObject class that are renamed so that they no
* longer begin with the underscore(_) character.
*
* For more information, see the "Display Programming" chapter of the
* _ActionScript 3.0 Developer's Guide_.
*
* @event added Dispatched when a display object is added to the
* display list. The following methods trigger this
* event:
* `DisplayObjectContainer.addChild()`,
* `DisplayObjectContainer.addChildAt()`.
* @event addedToStage Dispatched when a display object is added to the on
* stage display list, either directly or through the
* addition of a sub tree in which the display object
* is contained. The following methods trigger this
* event:
* `DisplayObjectContainer.addChild()`,
* `DisplayObjectContainer.addChildAt()`.
* @event enterFrame [broadcast event] Dispatched when the playhead is
* entering a new frame. If the playhead is not
* moving, or if there is only one frame, this event
* is dispatched continuously in conjunction with the
* frame rate. This event is a broadcast event, which
* means that it is dispatched by all display objects
* with a listener registered for this event.
* @event exitFrame [broadcast event] Dispatched when the playhead is
* exiting the current frame. All frame scripts have
* been run. If the playhead is not moving, or if
* there is only one frame, this event is dispatched
* continuously in conjunction with the frame rate.
* This event is a broadcast event, which means that
* it is dispatched by all display objects with a
* listener registered for this event.
* @event frameConstructed [broadcast event] Dispatched after the constructors
* of frame display objects have run but before frame
* scripts have run. If the playhead is not moving, or
* if there is only one frame, this event is
* dispatched continuously in conjunction with the
* frame rate. This event is a broadcast event, which
* means that it is dispatched by all display objects
* with a listener registered for this event.
* @event removed Dispatched when a display object is about to be
* removed from the display list. Two methods of the
* DisplayObjectContainer class generate this event:
* `removeChild()` and
* `removeChildAt()`.
*
* The following methods of a
* DisplayObjectContainer object also generate this
* event if an object must be removed to make room for
* the new object: `addChild()`,
* `addChildAt()`, and
* `setChildIndex()`.
* @event removedFromStage Dispatched when a display object is about to be
* removed from the display list, either directly or
* through the removal of a sub tree in which the
* display object is contained. Two methods of the
* DisplayObjectContainer class generate this event:
* `removeChild()` and
* `removeChildAt()`.
*
* The following methods of a
* DisplayObjectContainer object also generate this
* event if an object must be removed to make room for
* the new object: `addChild()`,
* `addChildAt()`, and
* `setChildIndex()`.
* @event render [broadcast event] Dispatched when the display list
* is about to be updated and rendered. This event
* provides the last opportunity for objects listening
* for this event to make changes before the display
* list is rendered. You must call the
* `invalidate()` method of the Stage
* object each time you want a `render`
* event to be dispatched. `Render` events
* are dispatched to an object only if there is mutual
* trust between it and the object that called
* `Stage.invalidate()`. This event is a
* broadcast event, which means that it is dispatched
* by all display objects with a listener registered
* for this event.
*
* **Note: **This event is not dispatched if the
* display is not rendering. This is the case when the
* content is either minimized or obscured.

* bitmap-filled square shape to the vector render. If you attempt to set
* this property to an invalid value, Flash runtimes set the value to
* `BlendMode.NORMAL`.
*
* The `blendMode` property affects each pixel of the display

* Flash Player or Adobe AIR compares each constituent color of one pixel in

* value of the display object with the red value of the background, and uses
* the lighter of the two as the value for the red component of the displayed
* color.

/**
* All vector data for a display object that has a cached bitmap is drawn
* to the bitmap instead of the main display. If
* `cacheAsBitmapMatrix` is null or unsupported, the bitmap is
* then copied to the main display as unstretched, unrotated pixels snapped
* to the nearest pixel boundaries. Pixels are mapped 1 to 1 with the parent
* object. If the bounds of the bitmap change, the bitmap is recreated
* instead of being stretched.
*
* If `cacheAsBitmapMatrix` is non-null and supported, the
* object is drawn to the off-screen bitmap using that matrix and the
* stretched and/or rotated results of that rendering are used to draw the
* object to the main display.
*
* No internal bitmap is created unless the `cacheAsBitmap`
* property is set to `true`.
*
* After you set the `cacheAsBitmap` property to
* `true`, the rendering does not change, however the display
* object performs pixel snapping automatically. The animation speed can be
* significantly faster depending on the complexity of the vector content.
*
*
* The `cacheAsBitmap` property is automatically set to
* `true` whenever you apply a filter to a display object(when
* its `filter` array is not empty), and if a display object has a
* filter applied to it, `cacheAsBitmap` is reported as
* `true` for that display object, even if you set the property to
* `false`. If you clear all filters for a display object, the
* `cacheAsBitmap` setting changes to what it was last set to.
*
* A display object does not use a bitmap even if the
* `cacheAsBitmap` property is set to `true` and
* instead renders from vector data in the following cases:
*
*
* * The bitmap is too large. In AIR 1.5 and Flash Player 10, the maximum
* size for a bitmap image is 8,191 pixels in width or height, and the total
* number of pixels cannot exceed 16,777,215 pixels.(So, if a bitmap image
* is 8,191 pixels wide, it can only be 2,048 pixels high.) In Flash Player 9
* and earlier, the limitation is is 2880 pixels in height and 2,880 pixels
* in width.
* * The bitmap fails to allocate(out of memory error).
*
*
* The `cacheAsBitmap` property is best used with movie clips
* that have mostly static content and that do not scale and rotate
* frequently. With such movie clips, `cacheAsBitmap` can lead to
* performance increases when the movie clip is translated(when its _x_
* and _y_ position is changed).

/**
* An indexed array that contains each filter object currently associated
* with the display object. The openfl.filters package contains several
* classes that define specific filters you can use.
*
* Filters can be applied in Flash Professional at design time, or at run
* time by using ActionScript code. To apply a filter by using ActionScript,
* you must make a temporary copy of the entire `filters` array,
* modify the temporary array, then assign the value of the temporary array
* back to the `filters` array. You cannot directly add a new
* filter object to the `filters` array.
*
* To add a filter by using ActionScript, perform the following steps
* (assume that the target display object is named
* `myDisplayObject`):
*
* 1. Create a new filter object by using the constructor method of your
* chosen filter class.
* 2. Assign the value of the `myDisplayObject.filters` array
* to a temporary array, such as one named `myFilters`.
* 3. Add the new filter object to the `myFilters` temporary
* array.
* 4. Assign the value of the temporary array to the
* `myDisplayObject.filters` array.
*
* If the `filters` array is undefined, you do not need to use
* a temporary array. Instead, you can directly assign an array literal that
* contains one or more filter objects that you create. The first example in
* the Examples section adds a drop shadow filter by using code that handles
* both defined and undefined `filters` arrays.
*
* To modify an existing filter object, you must use the technique of
* modifying a copy of the `filters` array:
*
* 1. Assign the value of the `filters` array to a temporary
* array, such as one named `myFilters`.
* 2. Modify the property by using the temporary array,
* `myFilters`. For example, to set the quality property of the
* first filter in the array, you could use the following code:
* `myFilters[0].quality = 1;`
* 3. Assign the value of the temporary array to the `filters`
* array.
*
* At load time, if a display object has an associated filter, it is
* marked to cache itself as a transparent bitmap. From this point forward,
* as long as the display object has a valid filter list, the player caches
* the display object as a bitmap. This source bitmap is used as a source
* image for the filter effects. Each display object usually has two bitmaps:
* one with the original unfiltered source display object and another for the
* final image after filtering. The final image is used when rendering. As
* long as the display object does not change, the final image does not need
* updating.
*
* The openfl.filters package includes classes for filters. For example, to
* create a DropShadow filter, you would write:
*
* @throws ArgumentError When `filters` includes a ShaderFilter
* and the shader output type is not compatible with
* this operation(the shader must specify a
* `pixel4` output).
* @throws ArgumentError When `filters` includes a ShaderFilter
* and the shader doesn't specify any image input or
* the first input is not an `image4` input.
* @throws ArgumentError When `filters` includes a ShaderFilter
* and the shader specifies an image input that isn't
* provided.
* @throws ArgumentError When `filters` includes a ShaderFilter, a
* ByteArray or Vector.<Number> instance as a shader
* input, and the `width` and
* `height` properties aren't specified for
* the ShaderInput object, or the specified values
* don't match the amount of data in the input data.
