title: jqGrid column not aligned with column headers
body: <p>I'm using jqGrid 3.6.5 and IE8</p>
  
  <p>When setting <code>shrinkToFit: false</code> the columns are clearly not aligned with the column headers.<br>
  If I turn on <code>shrinkToFit: true</code> the problem disappears, but I lose the absolute sizing of the columns.<br>
  Resizing the columns (in code, or dynamically by the user) does not affect this problem.</p>
  
  <p>See image for illustration</p>
