Transform Feedback is the process of capturing Primitives generated by the Vertex Processing step (s), recording data from those primitives into Buffer Objects. This allows one to preserve the post-transform rendering state of an object and resubmit this data multiple times.

To affect screen space transformations, you need to premultiply. OpenGL doesn't provide a mode switch for the order of matrix multiplication, so you need to premultiply by hand.
