-Call I_PauseMouse prior to SDL_SetVideoMode to disable RawWin32Mouse's input handler. SDL_SetVideoMode reinitializes DirectInput, thrashing RawWin32Mouse's input handler in the process. I_ResumeMouse is called afterwards to reset RawWin32Mouse's input handler.
-This fixes the unresponsive mouse after toggling vid_fullscreen with RawWin32Mouse.
