Fixed display mode calculations for applications which are not DPI aware.
If your application wants to have access to the full resolution even when the system has DPI scaling enabled, call SetProcessDPIAware() before calling SDL_Init()

e.g.
	typedef BOOL (WINAPI *SetProcessDPIAware_t)(void);
	HMODULE hMod = LoadLibrary("user32.dll");
	if ( hMod ) {
		SetProcessDPIAware_t pSetProcessDPIAware = GetProcAddress( hMod, "SetProcessDPIAware" );
		if ( pSetProcessDPIAware ) {
			pSetProcessDPIAware();
		}
		FreeLibrary( hMod );
	}
