Subject: [SDL] [PATCH] DirectX and SDL_WINDOWID Hack

Hello, all. The IDirectInputDevice2_SetCooperativeLevel call in
SDL_dx5events.c expects to be passed a root-level HWND. More often than not,
a child window is used with the SDL_WINDOWID hack, causing the
IDirectInputDevice2_SetCooperativeLevel call to fail.

This is a small patch to SDL_dx5events.c v1.21 that fixes the problem by
retrieving a handle to the root-level ancestor of the current SDL_Window and
passing that handle to IDirectInputDevice2_SetCooperativeLevel.
