Fixed bug #901

Disable mouse event generation when state is not SDL_APPMOUSEFOCUS
If a Windows SDL application is minimised by using alt-tab, SDL_APPMOUSEFOCUS
is lost as part of the minimisation. Unfortunately, the directx driver doesn't
pay any attention to this state when generating mouse button events, so
clicking on the Desktop can cause mouse clicks in the SDL application, while
it's still minimised. The attached patch fixes this. It looks much more
complicated than it actually is due to indentation; here it is ignoring
whitespace:
