How to best get smooth scrolling in X?

Hi there

Subject should be easy, but is it? The requirements are no stuttering and 
no flashing. Is it possible? (Think a newsticker for this question; just 
scrolling a piece of text or an image, across an X window.

SDL does not give me a real doublebuffer. Does OpenGL work correctly in 
software mode or do I need hardware support? Other options? CGI? Xlib 

What are my options? 

This was _really_ easy to do with svgalib. Not so with X?
