PIVOT-891: Add double/triple click support in TextPane the same way it is
supported (now) in TextArea.
Double click selects the word immediately under/around the mouse pointer,
and triple click selects the line (paragraph) that is under the mouse.
Essentially we just duplicated the code from TextArea into TextPane with
appropriate (small) modifications for the difference in APIs.
