   // Description: Workaround for wxWidgets bug: Reentry in clipboard
   //  The wxWidgets bug http://trac.wxwidgets.org/ticket/16636 prevents
   //  us from doing clipboard operations in wxShowEvent and wxTimerEvent
   //  processing because those event could possibly be processed during
   //  the (not sufficiently protected) Yield() of a first clipboard
   //  operation, causing reentry. Audacity had a workaround in place
   //  for this problem (the class "CaptureEvents"), which however isn't
   //  applicable with wxWidgets 3.0 because it's based on changing the
   //  gdk event handler, a change that would be overridden by wxWidgets's
   //  own gdk event handler change.
   //  Instead, as a NEW workaround, specifically protect those processings
   //  of wxShowEvent and wxTimerEvent that try to do clipboard operations
   //  from being executed within Yield(). This is done by delaying their
   //  execution by posting pure wxWidgets events - which are never executed
   //  during Yield().
   // Author: Martin Stegh  fer <[email protected]>
   //  Bug-Debian: https://bugs.debian.org/765341
 
   // the actual creation/showing of the window).
   // Post the event instead of calling OnSize(..) directly. This ensures that
   // this is a pure wxWidgets event (no GDK event behind it) and that it
   // therefore isn't processed within the YieldFor(..) of the clipboard
   // operations (workaround for Debian bug #765341).
   // QueueEvent() will take ownership of the event
