* \brief A variable that dictates policy for fullscreen Spaces on Mac OS X.
*
* This hint only applies to Mac OS X.
*
* The variable can be set to the following values:
* "0" - Disable Spaces support (FULLSCREEN_DESKTOP won't use them and
* SDL_WINDOW_RESIZABLE windows won't offer the "fullscreen"
* button on their titlebars).
* "1" - Enable Spaces support (FULLSCREEN_DESKTOP will use them and
* SDL_WINDOW_RESIZABLE windows will offer the "fullscreen"
* button on their titlebars.
*
* The default value is "1". Spaces are disabled regardless of this hint if
* the OS isn't at least Mac OS X Lion (10.7). This hint must be set before
* any windows are created.
