/*
2005 Kevin Ferrare :
 - Multi screen support
 - Rewrote a lot of code to avoid global vars and make it accept eventually
   more that 3 buttons on the bar (just the prototype of gui_buttonbar_set
   and the constant BUTTONBAR_MAX_BUTTONS to modify)
2008 Jonathan Gordon
 - redone to use viewports, items will NOT scroll in their vp.
   Bar is always drawn at the bottom of the screen. This may be changed later.
   Callers need to remember to adjust their viewports to not be overwitten
