// DESCRIPTION:
//	 All the global variables that store the internal state.
//	 Theoretically speaking, the internal state of the engine
//	  should be found by looking at the variables collected
//	  here, and every relevant module will have to include
//	  this header file.
//	 In practice, things are a bit messy.
