    Subject: [SDL] Request: Please reconsider adding tag in SDL_Event
    
    Hi,
    
    Patch in question:

      } SDL_SysWMEvent;
    
      /* General event structure */
    -typedef union {
    +typedef union SDL_Event {
             Uint8 type;
             SDL_ActiveEvent active;
             SDL_KeyboardEvent key;
    
    Reasoning:
    ----------
    1) Allows forward declaration of the SDL_Event union in C++. Please
    note that in plain C it is possible to forward declare it.
    
    2) Forward declaration is good because it allows encapsulation. It hides
    the specific implementation and does not necessarily exposes SDL staff
    to my appication's namespace
    
    3) It can't harm plain C because tags are living in a different namespace
    than typenames
    
    4) It is already done like this in other places in SDL. Check for example
    SDL_KeySym, and SDL_.*Event structures.
    
    5) Right now I have to include SDL/event.h from a C++ header file. See 2)
