MULTITHREADING NOT WORKING - OpenGL calls do not work properly called from a thread different from the one that OpenGL was initialized in. But, I need SDL calls to be called from the thread that SDL was initialized in, which is the thread that initializes OpenGL. That means that in order to use multithreading all OpenGL and SDL calls would have to be done from the main thread and not from the lua thread. This means that every single draw operation would have to be passed from the lua thread to the main thread for execution. This is a bad idea. So, I am going to revert all of these changes for multithreading and look into lua_sethook() for handling infinite loops instead.
