Column statistics dialog
************************

The column statistics dialog, launched from the file properties dialog
or by long-pressing a column header, shows summary statistics about
the data in a column.  Only data in rows that pass the current filter
is included in the calculations.  If it was launched from the file
properties dialog, a droplist at the top of the dialog allows you to
select which column to view statistics for; only columns in the
current view are listed.  At the bottom of the dialog is a widget
which allows you to edit the display width (in pixels) of that column
in the current view.  If you close the dialog by clicking "OK"/"Done",
any changes you made to the column widths will be applied.
