[Pharo-project] alwaysHideScrollbar, alwaysShowHScrollbar and alwaysShowVScrollbar

Hi all, sorry for all these annoying questions ... I would simply like to remove these preferences with: alwaysHideScrollbar always false alwaysShowHScrollbar always true alwaysShowVScrollbar always true. I can easily put new settings for them but is it really mandatory ? Instead, removing them let the opportunity to replace ScrollPane/ScrollBar with GeneralScrollPane/GeneralScrollBar (which are unused whereas it seems to me that they are cleaner and more simple) what do you think ? thanks Alain
