Description

The fix for #17 broke the Event.count for mouse wheel events. In internal.win32.OS.d the code needs to be changed like so: 

public static int GET_WHEEL_DELTA_WPARAM(int /*long*/ wParam){
    //return  HIWORD(wParam); // no good any more
    return  wParam >> 16;  // this works
}

Thanks Bill.

Google Codesearch gave me for the original macro this implementation: 

#define GET_WHEEL_DELTA_WPARAM(wParam)  ((short)HIWORD(wParam))

So i added the cast instead. See rev 51a84342d244.
