// HIWORD is typically used to detect whether a pointer parameter
// is a real pointer or is a MAKEINTATOM.  HIWORD64 is the Win64-compatible
// version of this usage.  It does *NOT* return the top word of a 64-bit value.
// Rather, it returns the top 48 bits of the 64-bit value.
//
// Yes, the name isn't very good.  Any better ideas?
//
// BOOLFROMPTR is used when you have a pointer or a ULONG_PTR
// and you want to turn it into a BOOL.  In Win32,
// sizeof(BOOL) == sizeof(LPVOID) so a straight cast works.
// In Win64, you have to do it the slow way because pointers are 64-bit.
