[SDL] Background picture and OpenGL

[Bruce @ OpenGL]

Make a huge quad that covers the entire window area and then apply your 
texture on it.
It is only a OpenGL issue, not a SDL one. Remember that your textures 
sides must be in power of 2 so OpenGL can render it.
That quad will have a Z value higher than the other objects in your 
scene so it appears to be in the background.

Hope this help,
Bruce Sinner
