[SDL] OpenGL & SDL Blitting w/ Alpha

[Dave Schmitz]

Hello.....

I am looking into the new  combined OpenGL 3D rendering and SDL 2D
blitting capabilities... This functionality is made available through
the use of SDL_SetVideoMode with the SDL_OPENGLBLIT option.

I noticed in a few demos that any alpha information is say a surface
that is being blitted is lost when using the SDL_OPENGLBLIT mode.  A
couple questions -

Currently is there anyway to make this work without going entirely to
OpenGL  (i.e. glDrawPixels or glTexImage2D ) so that a 2D blitted SDL
surface "blends" with an OpenGL rendered scene?

If not, any chance at getting this added or at least a pointer to where
would be a good place to start?????

Open to all suggestions....

Thanks,

  -Smitty
