Well, there is DGA, but I have no idea about it's current state WRT 
driver support (accelerated blits, that is), windowing support, 
security issues etc.

XRender seems to be the proper way of doing it now, but I'm not sure 
about the state of driver support. Never seen it fully accelerated 
myself, and I'm not even sure it's possible unless you happen to have 
the "right" video card. (The only sensible option would be 
implementing it over OpenGL, it seems to me. As long as all serious 
hardware is closed, we're not going to see any serious drivers for 
anything else.)

So, I would suggest OpenGL. It's *the* API for serious accelerated 
rendering, and there are tried and tested drivers for most video 
cards.

If you still want to use the SDL API, you might get away with using 
glSDL (wrapper or backend patch), until SDL 1.3/2.0 (which has 
renderers for OpenGL and Direct3D) is mature enough.
