The primary compositing backend is the OpenGL-based one, which should be more powerful and also possibly better documented. This backend is mostly for cases when the OpenGL backend cannot be used for some reason (insufficient performance, no usable OpenGL support at all, etc.) The plan is to keep it around as long as needed/possible, but if it proves to be too much hassle it will be dropped in the future.
