title: Is it possible to use StyledCellLabelProvider.COLORS_ON_SELECTION with a DecoratingStyledCellLabelProvider?
body: <p>I just found mention of how to keep background cell color even while hovering or selecting a row on a JFace TableViewer by using <code>StyledCellLabelProvider.COLORS_ON_SELECTION</code>. However, I am using a subclass of <code>StyledCellLabelProvider</code> - a <code>DecoratingStyledCellLabelProvider</code>. </p>
  
  <p>Is there any way for me to use the <code>StyledCellLabelProvider.COLORS_ON_SELECTION</code> style bit? I don't see any constructors that take a style bit, and no method to set the style.</p>
