TSRVCaretPen = class (TPen)
property CaretPen: TSRVCaretPen;
If CaretPen.Width = 0 (default), the system caret thickness is used (defined in the "Ease of Access" of the Settings app (or the Control Panel, depending in the Windows version)).
CaretPen.Color and Mode are ignored (the caret always uses Mode = pmNot)
