Description of Problem:

When using a non-standard listitem height the sub items are not vertically
aligned correctly. However the first column is aligned correctly.

Sample Code.

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


public class test
{
        static void Main ()
        {
                Form f = new Form ();

                ImageList imgList = new ImageList();
                imgList.ImageSize = new Size(1, 32);

                ListView lv = new ListView();
                lv.Dock = DockStyle.Fill;
                lv.Columns.Add(new ColumnHeader());
                lv.Columns.Add(new ColumnHeader());        
                lv.View = View.Details;
                lv.FullRowSelect = true;
                lv.SmallImageList = imgList;
                for (int i = 0; i < 20; i++)
                {
                        ListViewItem item = lv.Items.Add("Item");
                        item.SubItems.Add("123");
                }

                lv.Parent = f;
                Application.Run (f);
        }
}


Actual Results:
First column is aligned, others are not.

Expected Results:
All columns aligned the same (vertical center)

How often does this happen? 
Every time.


Additional Information:

This following code appears to fix the problem.
