Keep track of per-column information inside the listview.

Cache header rectangles.
Used the cached info instead of calling to the header each time.
Update the listview as we track column width changes.
Unify column handling between {Insert,Delete}Column, and width
changes.
Simplify RefreshReport, by using the new column info.
