I just submitted a new component to the Downloads section of the Lazarus website. It's also available on my site at:
http://tony.maro.net/mod.php?mod=downloads&op=showcat&id=2&level=1

TTilePanel

Displays a tiled graphic on a panel descendant, allowing for an offset that lets you do simple scrolling effects. It's nothing special, but it's aiight.

It's ready to be added to your IDE, but I haven't created an icon for it. A sample application is included that shows how to display a scrolling graphic with it from a resource file.
