(I cannot try the repro now, hence I'm just forwarding a bug report from local
community.)

The following sample code uses scale transform using System.Drawing, and gives
different graphics output than GDI+.

----
using System;
using System.Drawing;
using System.Windows.Forms;

class Test : Form {
 static void Main() {
   Application.Run(new Test { ClientSize = new Size(100, 100) });
 }
 protected override void OnPaint(PaintEventArgs e) {
   e.Graphics.ScaleTransform(100, 100);
   using (var pen = new Pen(Color.Red, 0.08f))
     e.Graphics.DrawLine(pen, 0, 0, 1, 1);
 }
}

----

The outputs from .NET (expected), Wine+mono on Windows on FreeBSD (correct),
and mono on FBSD (actual) are being attached.
