  Fixed bug 4255 - SDL_GetGlobalMouseState() returns incorrect Y on secondary display
  
  Julian Raschke
  
  I use an open Mac laptop with an additional external monitor. The coordinate spaces from SDL_GetGlobalMouseState() and SDL_GetWindowPosition() match on the primary display, but not on the secondary display.
  
  Cocoa window coordinates are vertically flipped in relation to the primary display:
  
  https://github.com/spurious/SDL-mirror/blob/release-2.0.8/src/video/cocoa/SDL_cocoawindow.m#L219-L222
  
  However, Cocoa_GetGlobalMouseState inverts the cursor Y coordinate per-display:
  
  https://github.com/spurious/SDL-mirror/blob/release-2.0.8/src/video/cocoa/SDL_cocoamouse.m#L320-L323
  
  Suggested fix: Replace the for-loop with this simpler calculation:
  
      *x = (int) cocoaLocation.x;
      *y = (int) (CGDisplayPixelsHigh(kCGDirectMainDisplay) - cocoaLocation.y);
