Text Align Center is "one character" to the right #80

Text Align Center seens to be "1 character" to the right than the real center!

The bug is with TextWidth Function, that is returning the wrong size (Try to 
draw a FrameRect in the font, and you will see that the framerect is smaller 
than the Font).

Parcial fix for this is :

function TPHXFont.TextExtent(const Text: AnsiString): TVector2i;
var Index    : Cardinal;
var Character: Integer;
var LineWidth: Integer;
begin
  // No text
  if Length(Text) = 0 then
  begin
    Result.X:= 0;
    Result.Y:= 0;

    Exit;
  end;

  // Get the first character
  Character:= CharacterMap[ Ord( Text[1] ) ];
  // Compensate for the offset of the first character
  Result.X:= FCharacters.List^[Character].Width -    FCharacters.List^[Character].XAdvance - FCharacters.List^[Character].XOffset;

  Result.Y:= Metric.Height;
