Hi everyone!
Results after using these functions of XGraphics vary from results which we get from .NET Graphics functions BeginContainer(...), EndContainer().
Is it bug or feature?

This is an extract from my WinForms application:

override protected void OnPaint(PaintEventArgs e)
{
// Create a new PDF document
PdfDocument document = new PdfDocument();

// Create an empty page
PdfPage page = document.AddPage();

XGraphics gfx = XGraphics.FromGraphics(e.Graphics, new XSize(100, 100));



// Define transformation for container.
Rectangle srcRect = new Rectangle(0, 0, 200, 200);
Rectangle destRect = new Rectangle(100, 100, 150, 150);

// Begin graphics container.
XGraphicsContainer containerState1 = gfx.BeginContainer(
destRect, srcRect,
XGraphicsUnit.Point);

// Fill red rectangle in container.
gfx.DrawRectangle(new SolidBrush(Color.Red), 0, 0, 200, 200);

// End graphics container.
gfx.EndContainer(containerState1);

// Begin graphics container.
GraphicsContainer containerState2 = e.Graphics.BeginContainer(
destRect, srcRect,
GraphicsUnit.Point);

// Fill red rectangle in container.
e.Graphics.FillRectangle(new SolidBrush(Color.Black), 0, 0, 200, 200);

// End graphics container.
e.Graphics.EndContainer(containerState2);




// Save the document...
const string filename = "C:\\HelloWorld_tempfile.pdf";
document.Save(filename);
// ...and start a viewer.
//Process.Start(filename);
}

I think it's a bug (my boss will have to look at it, but he's currently unavailable).
