Do you want to have basic 2D GDI like or do
you want to have HW Surfaces and that things ?

Two ways :

1. With a compat. header it maybe no problem
to compile an executable with SDL 1.2 and 1.3.

2. The SDL 1.2 2D drivers could be added to SDL 1.3.
As every 3D code naturally has to check if the spec.
3D API OGL or D3D is available.

That was my hope that SDL supports a transparent way of rendering.

SDL inits 3D. In my mainloop
I do all my 3D calls and as a last call before SDL_Flip
i call for example SDL_Do2D or whatever, it blits the 2D stuff.
