Sometimes, there needs to be code that gets ran at the end of the game loop, otherwise rendering issues might occur. Currently, we do this by special-casing each deferred routine (e.g. shouldreturntoeditor), but it would be better if we could generalize this deference instead. Deferred callbacks can be added using the DEFER_CALLBACK macro. It takes in one argument, which is the name of a function, and that function must be a void function that takes in no arguments. Also, due to annoying C++ quirks, void functions taking no arguments cannot be attributes of objects (because they have an implicit `this` parameter), so it's recommended to create each callback separately before using the DEFER_CALLBACK macro.
