Hi,  
i try to do a text parser for utils/text-scroller.cc because we can’t see all of the string when his length is bigger than the panel length.  
Please help me for that parser.

(ex: panel 32x32 → Hi my name is Ben  
i want on the pannel:  
Hi my  
name  
is  
Ben)

This might be overkill, but if you look at one of my programs you will find the commands I use to scroll text vertically, just like you are saying.
