We can add any preamble or post-amble code we want to
SWFWriter.openSnippet() and closeSnippet(). These get called at the
start end end of generating code for libraries.
There's already a line of script that gets added as the final code to
execute when a library loads, which is the callback to let the LFC
know it has finished loading:

    public void closeSnippet() throws IOException {
        // Make sure we stop
        addScript("this._parent.loader.snippetLoaded(this, null)");
        Program program = new Program();
        program.stop();
        program.none();
        addProgram(program);
