  DELPHI 1.0

  Two new freeware components based on TSpeedButton and TBitBtn.  The most
  improvement is the ability to put an Icon replacing the only BMP picture.

  On somes ICON,  the result  is not  very good  but in the most case, the
  result is great.


  TAVCSpeedButton:

      - PopupMenu Feature
      - Icon

  TBitBtn:

      - Icon


   Sample:
   ------

   var
      btTry: TAVCSpeedButton;

   ...

      btTry.LoadIcon (LoadIcon(hInstance, 'MAINICON'));
