[lazarus] TMenuItem Delphi incompatibility

[Martin Smat]

Hi,
in LCL is declared property TMenuItem.Graphic:  TGraphic;
in Delphi is declared property TMenuItem.Bitmap: TBitmap;

In Lazarus is not possible to get the icon handle without typecasting 
(menuitem.Graphic as TBitmap).Handle;

Can it be changed or has it any reason?
