It seems that sdl_gfx has been ported to sdl2 http://sdl.5483.n7.nabble.com/Interpolate-and-SDL-2-0-alternatives-to-sdl-gfx-features-td37500.html Might it be that something has to be added to the core to get decent primitive support? PySDL2 seems to wrap the port http://pysdl2.readthedocs.org/en/latest/modules/sdl2_sdlgfx.html is that what you're referring to when you say things are worse?
This thread is also interesting: http://forums.libsdl.org/viewtopic.php?p=33873&sid=a3c6a0cf0146ed93007c8963e8cad3b1 It suggests there's scope for two gfx libraries: a software-based one that is feature complete and robust, and a OpenGL-based version that's faster but harder to work with.
