* forward declaration of SDL_Event

// 2006-08-26 SDL is dragged into 6 of our 7 static library components.
// it must be specified in each of their "extern_libs" so that the
// include path is set and <SDL.h> can be found.
//
// obviously this is bad, so we work around the root cause. mostly only
// SDL_Event is needed. unfortunately it cannot be forward-declared,
// because it is a union (regrettable design mistake).
// we fix this by wrapping it in a struct, which can safely be
// forward-declared and used for SDL_Event_* parameters.
