The four new parameters RGBbgTotals, RGBfgTotals, RGBbgHeaders, RGBfgHeaders all take the argument =r,g,b
They establish the base colors for the special data lines at the top and bottom of the tree which have been flagged as headers or totals.
Note that totals line(s) are defined via the XTF_TOTALS flag and/or TotalLines=# coldef parameter; headers lines are defined by the HeaderLines=# coldef parameter.
Also note that "header" lines defined via HeaderLines=# should not be confused with the real column headers, which are not data lines at all and which do not have adjustable colors. The header lines we're talking about here are just data lines that have been designated "headers" so that they remain at the top, regardless of sorting.
