  10.     Change History (most recent first):
  11.  
  12.         <14>     2/17/94    JA        Declare XMPPolygon as struct, not class.
  13.         <13>     2/16/94    JA        Stop including Point.h.
  14.         <12>      2/3/94    JA        Tiger Team Makeover!
  15.         <11>      2/1/94    JA        Added InitShape, removed comments.
  16.         <10>     1/31/94    JA        Added GeometryMode stuff. Changed XMPShape*
  17.                                     return types.
  18.          <9>    11/23/93    JA        New Shape API (big changes!)
  19.          <8>    10/14/93    JA        Updated some comments for clarity.
  20.          <7>    10/14/93    JA        Rewrote theory (copying now optional.)
  21.          <6>     10/6/93    JA        Include new "Point.h"
  22.          <5>     9/16/93    JA        Removed ExtractPlatformShape. Added IsEmpty
  23.                                     and Read/WritePlatformShape. Removed
  24.                                     constructor w/params (it could fail).
  25.          <4>      7/6/93    JBS        separate into abstract/concrete
  26.          <3>     4/30/93    JBS        8.3 file names
  27.          <2>     4/14/93    JBS        clean up; add ExtractPlatformShape()
  28.          <1>     4/14/93    JBS        first checked in
