Description Dirk Fauth

If you have a setup with performance column groups and freeze support, you can collapse a group in frozen state. But if you try to reorder the group the rendering breaks. This gets up to the point that some columns are not visible anymore or columns are doubled.

The reason is in AbstractColumnHideShowLayer. When transforming the column indexes to positions, the negative values for hidden columns are not respected. This is probably due to the fact that typically you can only reorder visible columns. But in case of the ColumnGroupHeaderLayer and collapsed groups, it is also possible to reorder hidden columns.
