MOVESIZEDATA Flags

The ancient MOVESIZEDATA structure has long had a set of flags. Type information in symbol files for WIN32K.SYS in Windows 7 (only) enumerates the defined flags as UINT bit fields in union with a Flags member that is itself a ULONG. Inevitably, many more have been defined since. It seems unlikely that I shall ever attempt to describe the additions, let alone attempt an enumeration of which flags are defined in which versions, but you never know.
