PenAlignment behaviour

[crater]

I'm writing a graphical control that can have a border with a widt
of 1 to 10 pixels. My control is derived from System.Windows.Forms.Control

I would have expected the following method to
accomplish the task..

private void DrawBorder(Graphics g

using (Pen pen = new Pen(BorderColor, BorderWidth

pen.Alignment = PenAlignment.Inset
g.DrawRectangle(pen, this.ClientRectangle)

.... however, with a borderwidth of 1 pixel, the border is drawn
outside the control at the right and bottom sides. What I ende
up having to do is the following..

private void DrawBorder(Graphics g

using (Pen pen = new Pen(BorderColor, BorderWidth

int Offset = BorderWidth >> 1
g.DrawRectangle(pen, Offset, Offset
this.Width - BorderWidth
this.Height - BorderWidth)

Has anyone else come across funnies with Pen alignment??
