Subject: Added and implemented arrows that appear when scrolling is possible in an infobox... 
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=89afae628ef9bf46b66f42a2573f6abc5f9bcb61;p=supertux.git

Added and implemented arrows that appear when scrolling is possible in an infobox. Feel more than free to redo the arrow images -- mine are there only for testing.
