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.

sdlgfx is already in extras. Or is this something diffrent?

No, that should be the same. Strange enough, when I checked with "apt-cache search" on my tablet, I was not able to find the packages.
