Subject: [PATCH] Always call destroy on local render script object

StrictMode reports that the local rs object leaks memory if it does not call destroy on the local reference. Always calling destroy() explicitly (when not null) fixes this memory leak.

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.
    java.lang.Throwable: Explicit termination method 'destroy' not called
