Description yeray alonso 2014-08-04 08:01:18 EDT 
Multi-line node text not correctly displayed, if the line count is even.
Code to reproduce:

procedure TForm1.FormCreate(Sender: TObject);
var i: Integer;
begin
  TreeNodeShape1.Text.Clear;
  for i:=1 to 10 do
   TreeNodeShape1.Text.Add('Line ' + IntToStr(i));
end;

Fix suggested by the customer:
At line 4164 in TeeTree.pas, function TTreeNodeShape.DrawText reads:

vtaCenter: tmpPosY:=tmpMidY + Round( (t*tmpH) - ((tmpCount div 2)*tmpH) - (tmpH*0.5) );

Change the above for this to fix the problem:

vtaCenter: tmpPosY:=tmpMidY + Round( (t*tmpH) - ((tmpCount div 2)*tmpH) - (tmpCount mod 2)*(tmpH*0.5) );
