I updated it to this now:

http://wiki.allegro.cc/index.php?title=RenderState

So basically, still only one function called

al_set_render_state

but with no negative flags and more proper (OpenGL-like) naming. It
also supports separate color channels again and also alpha testing.

I'm seeing if I can get a Direct3D implementation of it working in Wine
today.
