// The Module object: Our interface to the outside world. We import
// and export values on it. There are various ways Module can be used:
// 1. Not defined. We create it here
// 2. A function parameter, function(Module) { ..generated code.. }
// 3. pre-run appended it, var Module = {}; ..generated code..
// 4. External script tag defines var Module.
// We need to check if Module already exists (e.g. case 3 above).
// Substitution will be replaced with actual code on later stage of the build,
// this way Closure Compiler will not mangle it (e.g. case 4. above).
// Note that if you want to run closure, and also to use Module
// after the generated code, you will need to define   var Module = {};
// before the code. Then that object will be used in the code, and you
// can continue to use Module afterwards as well.
#if USE_CLOSURE_COMPILER
// if (!Module)` is crucial for Closure Compiler here as it will otherwise replace every `Module` occurrence with a string

// meant to overwrite the default module functionality. Here
// we collect those properties and reapply _after_ we configure
// the current environment's defaults to avoid having to be so
