labels overlapped by the chart when LabelsAngle is oblique

The labels position seems to be wrong when LabelsAngle is oblique.
The problem is reproducible with the code below from v2013.09. It worked fine with v2013.08.

  Chart1.View3D:=false;

  with Chart1.AddSeries(TBarSeries) as TBarSeries do
  begin
    ColorEachPoint:=true;
    for i:=0 to 5 do
     Add(5+random*10, 'my label nº' + IntToStr(i));
  end;

  Chart1.Axes.Bottom.LabelsAngle:=45;

Refactored and fixed.
Improved labels alignment to axis ticks for any given angle (0 to 360 degree) and both horizontal and vertical axes.
