Test case

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr; rv:1.9.2)
Gecko/20100115 Firefox/3.6

Using the DrawLine method of a Graphics object, the line drawn is horizontally
misplaced if the Pen has a width higher than 1. It is shifted to the right by 1
pixel.

The attached test case shows this issue (it zooms the result by a factor of 2
to make it clearer).

Reproducible: Always
