I am thinking about using SDL_gfx for a project, so I've taken the Debian source package and uploaded it to Maemo Extras. It's in Extras-Devel now, and after some testing I'll promote it to Maemo Extras.

..if anybody wants to use that library in their game.

SDL_gfx provides functions like rotozoom for surface rotation and zooming in software.
