/**

 *         This file contains methods that provides the functionality for

 *********************************************************************************************
 This is the proxy specific wrapper that passes the component name to the generic proxy init()
 The proxy wrapper also does some runtime/static time onfig on per proxy basis
 This is a thin wrapper that is called when componentiit() of the proxy is called
 static OMX_ERRORTYPE PROXY_Wrapper_init(OMX_HANDLETYPE hComponent, OMX_PTR pAppData);
 this layer gets called first whenever a proxy's get handle is called
