/*
|
|
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
