..
CustomScaleManager	Allows the application's scale to be set manually to a specific value, instead of calculating it automatically, like other scale managers. Defaults to automtically calculating the application dimensions to fill the stage dimensions, but can optionally accept custom application dimensions too.
DefaultFocusManager	The default implementation of `IFocusManager`.
DefaultPopUpManager	The default implementation of the `IPopUpManager` interface.
DefaultToolTipManager	The default implementation of `IToolTipManager`.
FeathersControl	Base class for all Feathers UI controls. Implements invalidation for changed properties and sets up some basic template functions for component lifecycle, like `initialize()` and `update()`.
FocusManager	Manages mouse/touch and keyboard focus.
IDataSelector	Provides a selection from a collection of items.
IDateSelector	Provides a selection from a range of dates.
IFocusContainer	A component that may receive focus that also has children that may receive focus.
IFocusExclusions	A container that may exclude some children from receiving focus.
IFocusExtras	A container that may have extra children that aren't accessible from the standard display list functions like `getChildAt()`, but those "extra" children may still need to receive focus. An example of this would be a container with "chrome", such as the header and footer in `feathers.controls.Panel`.
IFocusManager	Manages focus of UI components.
IFocusManagerAware	A component that has access to a focus manager, but cannot necessarily receive focus.
IFocusObject	A component that may receive focus from a focus manager.
IHTMLTextControl	A user interface control that displays HTML text.
IIndexSelector	Provides a selection from a range of integers.
IMeasureObject	A display object with extra measurement properties, including minimum and maximum dimensions.
IOpenCloseToggle	A UI component that may be opened or closed.
IPointerDelegate	Used by components, like data renderers, to delegate pointer state to another interactive display object. For instance, the cell renderers in the `GridView` and `TreeGridView` components delegate pointer state to their parent row.
IPopUpManager	Manages pop-ups for all children of a root component (usually, all children of a `Stage`).
IScaleManager	Determines how an application is scaled and how its dimensions are set.
IStageFocusDelegate	Allows a different interactive display object to receive stage focus when this object receives focus from a focus manager.
IStateContext	An object with multiple states.
IStateObserver	Watches an `IStateContext` for state changes
ITextControl	A user interface control that displays text.
IToolTipManager	Manages tool tips for UI components.
IUIControl	A user interface control.
IValidating	A display object that supports validation. Display objects of this type will delay updating after property changes until just before OpenFL renders the display list to avoid running redundant code.
InvalidationFlag	Flags that are used internally with `FeathersControl.invalidate()` to track of which parts of the component need to be updated. These flags are merely suggestions, and custom components may support custom flags.
LetterboxScaleManager	Ensures that the application has the same internal width and height on all devices, while scaling it larger or smaller to fit within the bounds of the stage. The application may be letterboxed on some screens, which means that there may be some empty space on the top and bottom, or on the left and right, of the application's bounds within the window. The application will always be centered within the stage bounds.
MeasureSprite	An `openfl.display.Sprite` with extra minimum and maximum dimensions that may be used in Feathers UI layouts.
PopUpManager	Adds a display object as a pop-up above all other content on the stage.
ScreenDensityScaleManager	Uses the device's screen density (sometimes called the DPI or PPI) to calculate the ideal scale value for the application. The dimensions will be calculated so that the application fills the entire stage, regardless of the screen resolution of the device (or the size of the window, where appropriate). With this in mind, it's best to use fluid layouts, to account for differences in screen resolution and aspect ratios.
ToggleGroup	Controls the selection of two or more IToggle instances where only one may be selected at a time.
ToolTipManager	Manages tool tips for UI components.
ValidatingSprite	An `openfl.display.Sprite` with a validation system where multiple property changes may be queued up to be processed all at once. A performance optimization for frequently changing user interfaces.
ValidationQueue	A queue for components that are invalid.
