  by Oleksandr Grebenyuk.

  The folowing macro demonstrated the problem:

  {
   TCanvas *c1 = new TCanvas("c1", "c1",521,150,700,590);
   c1->Range(0,0,1,1);

   TPaveText *pt;
   TText     *text;

   pt   = new TPaveText(0.1106322,0.6004274,0.8448276,0.9764957,"br");
   text = pt->AddText("Calculate from helvetica bold");
   text = pt->AddText("Display with helvetica bold");
   pt->Draw();

   pt   = new TPaveText(0.112069,0.1325301,0.8477011,0.5562249,"br");
   pt->SetTextFont(22);
   text = pt->AddText("Calculate from helvetica bold");
   text = pt->AddText("Display with times bold");
   pt->Draw();

   TLine *line = new TLine(0.8132184,0.9558233,0.8132184,0.2309237);
   line->SetLineColor(2);   line->Draw();
   line = new TLine(0.783046,0.5140562,0.783046,0.2309237);
   line->SetLineColor(2);   line->Draw();
   TArrow *arrow = new TArrow(0.783046,0.2610442,0.8146552,0.2610442,0.02,"<|>");
   arrow->SetFillColor(2);   arrow->SetFillStyle(1001);
   arrow->SetLineColor(2);   arrow->Draw();
  }
