// deleted my previous comment because it wouldn't work for column index 0

Hello,

I just started using this library today, so I don't know if this is the best 
way to do it. I also don't actually know what bUseColVis does.  Anyway, I 
needed this done so I changed the _fnColumnIndex function and now you can 
specify "iFilterColumn" in aoColumns, and it works on hidden columns.  Only 
tested in Firefox on client side tables.

....
"aoColumns": [
 null,
 {'type': 'text'},
 null,
 {
 'type': 'select',
 'values': [
  {'value':'is_approved', 'label': 'Approved'},
  {'value':'not_approved', 'label': 'Not Approved'}
 ],
 'iFilterColumn': 2
},
...

function _fnColumnIndex(iColumnIndex) {
 if (properties.bUseColVis) {
  // this if is the new part
  if (typeof properties.aoColumns[iColumnIndex].iFilterColumn !== 'undefined'){
   return properties.aoColumns[iColumnIndex].iFilterColumn;
  }
  return iColumnIndex;
 } else {
  return oTable.fnSettings().oApi._fnVisibleToColumnIndex(oTable.fnSettings(), iColumnIndex);
 }
}

Criticism welcome.

Jared
