SDL_GetDisplayUsableBounds - Get the usable desktop area represented by a display, in screen coordinates.

       This function is available since SDL 3.2.0.

       This  is  the  same  area  as  SDL_GetDisplayBounds()  reports,  but with portions reserved by the system
       removed. For example, on Apple's macOS, this subtracts the area occupied by the menu bar and dock.

       Setting a window to be fullscreen generally bypasses these unusable areas, so these are  good  guidelines
       for the maximum space available to a non-fullscreen window.

displayID
              the instance ID of the display to query.

       rect   the SDL_Rect structure filled in with the display bounds.
