Actually, the GL-context is almost only used to swap the buffers, so
passing the context to the engine if the engine doesn't call the
swap_buffers() functions is not really coherent I think.
And since there is no generic GL-context type (each windowing system
implements its own type for the GL-context: GLXContext for GLX, HGLRC
for Windows...), we still couldn't have a generic GL-engine (we would
still need one GL-engine per windowing system).
