That, at least, was solved relatively painlessly.  Before I realized 
there were two different classes handling the rendering, I forced the 
first column to my patched regular ADGItemRenderer (because that put 
the color in more rows in that column).  So the only time it used my 
GroupItemRenderer was when it actually was displaying a group, which 
seems to override the hardcoded itemRenderer.
