fixed transcript widget configuration (on Windows)

 * widget configuration in size allocation depends on widget being realized
 * widget realization depends on the widget being size allocated
 * at least on Windows, the size is not reallocated after widget
realization (except of course it is actually resized)
 * so a _reconfigure() function has been introduced (does the same as configure-event handler would do)
