Hi,
PdfGraphicsState.AddTransform using only XMatrixOrder.Prepend, so it has a different result when trying to run the code in 1.32 and 1.5 versions:

XFont fontRegular = new XFont("Times New Roman", 20, XFontStyle.Regular);

state = gfx.Save();
gfx.TranslateTransform(100, 100);
gfx.ScaleTransform(0.5, XMatrixOrder.Prepend);
gfx.DrawString("Test1", fontRegular, XBrushes.DarkSlateGray, 0, 30);
gfx.Restore(state);

state = gfx.Save();
gfx.TranslateTransform(200, 200);
gfx.ScaleTransform(0.5, 0.5, XMatrixOrder.Append); //<==== here we have got difference
gfx.DrawString("Test3", fontRegular, XBrushes.DarkSlateGray, 0, 30);
gfx.Restore(state);
state = gfx.Save();

Is there is a reason why append is not processed like it is done in provided example (AddTransform.png)
