SDL is only a graphics framework in that it gives you a window, input events, and either a putpixel/blit functions or OpenGL. It does not have graphics primitives, like what used to be called "glut" in OpenGL itself (but supporting normal platforms, glut supported SGI Irix, BeOS and OS/2, but felt that Win32 was too niche to care about, and they never voluntarily cared about linux). Like even now it seems to think that this whole IOS and Android kerfuffle will blow over soon, not worth any effort. SDL is like a (much better) glut that has sane platform support (and audio). PanGUI gives you graphics primitives, nicely done and executed and seems to have a much saner selection of platforms (and also gives you audio), as well as supporting a great many languages to code in.
