// NOTE:  There are problems with iball.tlb containing definitions for
//  tagRECT and tagPOINT and thus in iball.tlh.  Therefore iball.tlh
//  must be wrapped in a namespace to avoid duplicate definitions.  Whence
//  the property Ball and method Reset are actually defined for 
//  BallLib::tagRECT and BallLib::tagPOINT.  This situation will be 
//  temporary, yet some inconvenience can be alleviated with the following
//  macros.
//    
#define CAST_RECT(x) reinterpret_cast<BallLib::tagRECT> (x)
#define CAST_POINT(x) reinterpret_cast<BallLib::tagPOINT> (x)
