* This is the "heart" of the id Tech 2 refresh engine. This file
* implements the main window in which Quake II is running. The window
* itself is created by the SDL backend, but here the refresh module is
* loaded, initialized and it's interaction with the operating system
* implemented. This code is also the interconnect between the input
* system (the mouse) and the keyboard system, both are here tied
* together with the refresher. The direct interaction between the
* refresher and those subsystems are the main cause for the very
* acurate and precise input controls of the id Tech 2.
