SDL_GetMouseState - Query SDL's cache for the synchronous mouse button state and the window-relative SDL-

       This function is available since SDL 3.2.0.

       This  function returns the cached synchronous state as SDL understands it from the last pump of the event
       queue.

       To query the platform for immediate asynchronous state, use SDL_GetGlobalMouseState.

       Passing non-NULL pointers to x or y will write  the  destination  with  respective  x  or  y  coordinates
       relative to the focused window.

       In  Relative  Mode,  the  SDL-cursor's  position  usually  contradicts  the platform-cursor's position as
       manually calculated from SDL_GetGlobalMouseState() and SDL_GetWindowPosition.

x      a pointer to receive the SDL-cursor's x-position from the focused window's top left corner, can be
              NULL if unused.

       y      a pointer to receive the SDL-cursor's y-position from the focused window's top left corner, can be
              NULL if unused.

       SDL_GetMouseState - Query SDL's cache for the synchronous mouse button state and the window-relative SDL-
       cursor position.

       Returns a 32-bit bitmask of the button state that can be bitwise-compared against the  SDL_BUTTON_MASK(X)
       macro.
