  10.     Change History (most recent first):
  11.     
  12.          <8>     1/20/95    DRF        Fix a double-dispose bug: there is no need to get rid of a
  13.                                     window’s picture. DisposeWindow will already KillPicture it.
  14.          <7>      1/3/95    DRF        Only show the splash window if there is a splash screen picture.
  15.          <6>    11/16/94    DRF        Add (StringPtr) cast to make PPCC happier.
  16.          <5>    11/12/94    DRF        Use NewColorOrBlackAndWhiteWindow.
  17.          <4>     11/8/94    DRF        Deal with a missing splash picture.
  18.          <3>     9/27/94    DRF         AppLib.h is now Sprocket.h
  19.          <2>      9/9/94    DRF        Reordered headers and removed redundant #includes.
