/**
* Extends UnityAppController to override shouldAttachRenderDelegate
* so that it can register a low-level rendering plugin.
*
* Unlike other platforms (like Desktop) where the plugin dynamic library is automatically
* loaded and registered by Unity, that must be done manually on iOS. VXWebViewAppController.mm uses Unity's
* IMPL_APP_CONTROLLER_SUBCLASS() macro to tell Unity to use VXWebViewAppController
* instead of UnityAppController. Due to a design flaw of Unity's plugin system for iOS, it's possible for
* multiple iOS plugins in a project to call IMPL_APP_CONTROLLER_SUBCLASS(), which results in one plugin's use
* of IMPL_APP_CONTROLLER_SUBCLASS() overwriting another's. For instructions on resolving such a conflict,
* please see this support article: https://support.vuplex.com/articles/ios-graphics-plugin-conflict
