LazFreeType glyph bounds incorrect

Original Reporter info from Mantis: circular

• Reporter name:

Description:

The bounds of the glyph are not computed correctly. It is due to 2 additional debug points added that need to be ignored when computing the bounds.

To fix, I suggest to add a parameter to the TT_Get_Outline_BBox function indicating the number of "phantom" points.

Steps to reproduce:

Run attached sample project and look at white area.

  function TT_Get_Outline_BBox( var out  : TT_Outline;
                                var bbox : TT_Bbox;
                                nbPhantomPoints : integer ) : TT_Error;
  var
    x,    y    : TT_Pos;
    n          : Int;
  begin

    with bbox do
    begin
      xMin := $7FFFFFFF;
      xMax := -$80000000;
      yMin := $7FFFFFFF;
      yMax := -$80000000;

      for n := 0 to out.n_points-1-nbPhantomPoints do
      begin
        x := out.points^[n].x;
        if x < xMin then xMin := x;
        if x > xMax then xMax := x;
        y := out.points^[n].y;
        if y < yMin then yMin := y;
        if y > yMax then yMax := y;
      end;
    end;

    TT_Get_Outline_BBox := TT_Err_Ok;
  end;
