Constructor
Methods
clearCache():Void
Special handling to ensure Flixel's aggressive Bitmap caches get cleared.
NOTE: You may need to manually remove certain images from the cache, if you created them based on an asset
(such as with FlxGraphic.fromFrame)
destroy():Void
Gets called when the backend is being destroyed.
This happens when Polymod.init() is called again, which means mods are being reloaded.
