Yes, the Visual module uses OpenGL.

My unexpert guess is that Visual isn't "extensible" to SDL, whatever that 
would mean. Visual implements a parallel thread that periodically reads the 
current values of the attributes of the graphics objects that have been 
created, and it paints a 3D scene using these current values. This makes 3D 
graphics be a side effect of computations. Architecturally, this is pretty 
different from other kinds of graphics environments.
