Description

	`constructor Create;`
This item has no description.

	`destructor Destroy; override;`
This item has no description.

	`function GetEnumerator: TEnumerator;`
This item has no description.

	`procedure DoChange;`
Calls OnChange.

	`function Count: Integer;`
Number of connected controllers.

	`procedure Initialize;`
Detect connected controllers now and keep updating this list when controllers are connected / disconnected. On some platforms, you need to call this to search for connected controllers, otherwise you will always have zero controllers. Calling this again is allowed and harmless.

	`function InternalExplicitBackend: TInternalControllerManagerBackend;`
Get (creating if necessary) explicit backend. Always returns TExplicitControllerManagerBackend, but cannot be declared as such. Used by CASTLE_WINDOW_LIBRARY when an external API notifies us about the controllers state.

	`property Items[const Index: Integer]: TGameController read GetItems;`
List of connected controllers. Use this to access individual controllers.

	`property Initialized: Boolean read FInitialized;`
Was Initialize called.

property OnChange: TNotifyEvent read FOnChange write FOnChange;

Called after TGameController instances on the list changed (some have been added, some destroyed).

This can be called at any moment, as controllers may be connected / disconnected at any moment.
