[Lazarus] Typo in TFPCustomFont?

[Felipe Monteiro de Carvalho]

Hello,

packages/fcl-image/src/fpcanvas.pp in FPC 2.6 (didn't yet check trunk) has:

  TFPCustomFont = class (TFPCanvasHelper)
  public
    property StrikeTrough : boolean index 8 read GetFlags write SetFlags;
  end;

Googling seams to indicate the correct should be "StrikeThrough", but
I'm not that great in english spelling, sometimes there is a american
and english variant, etc, so maybe someone could confirm what is the
correct? StrikeThrough or StrikeTrough?

And if it is really a typo, can I fix it even breaking compatibility?

thanks,
