+ * A variable controlling whether SDL will attempt to automatically set the

+ * The variable can be set to the following values:
+ *
+ * - "0": SDL will not attempt to automatically set a matching mode on the
+ *   destination display. If an exclusive fullscreen window is moved to a new
+ *   display, the window will become fullscreen desktop.
+ * - "1": SDL will attempt to automatically set a mode on the destination
+ *   display that most closely matches the mode of the display that the
+ *   exclusive fullscreen window was previously on. (default)

+ * This hint can be set anytime.
