Remove obsolete comments. The line they comment was kicked out of the code in [946e946700].
bug_fab5fed65e
Also, add a small optimization to avoid double invalidation of the damaged region. Indeed the detailed analysis of ticket [fab5fed65e] showed that on OS X the damaged region is invalidated twice:
- once through the processing of the Expose event (on OS X the Appkit is not used to draw the widget, Tk is used instead, see comments in tkMacOSXWindowEvent.c around line 770)
- a second time because DisplayText() calls TextInvalidateRegion() after TkScrollWindow()
