 *   rend:      Contains rendition information: font, bold, colour, etc.
 * * Note: Each line for both text and rend are only allocated on demand, and
 *         text[x] is allocated <=> rend[x] is allocated  for all x.

 *
 * selection_t elements
 *   clicks:    1, 2 or 3 clicks - 4 indicates a special condition of 1 where
 *              nothing is selected
 *   beg:       row/column of beginning of selection  : never past mark

 * * Note: -TermWin.nscrolled <= beg.row <= mark.row <= end.row < TermWin.nrow
 * * Note: col == -1 ==> we're left of screen

 * TermWin.saveLines:
 *              Maximum number of lines in the scrollback buffer.
 *              This is fixed for each rxvt instance.
