[SDL] off-screen buffer for openGL in SDL?

Hi, sorry if this question is answered somewhere in the
documentation, but I've looked and so far haven't found anything.
I need to create an off-screen buffer for openGL that is
(slightly) larger than the window I'm drawing--I'm doing some
image warping, and will be using the larger image as a texture,
doing some warping, and drawing it to the main window. Using
double-buffering, though, I can only draw an image as large as the
current window size. I need something similar to a pbuffer in
wgl, and was wondering if SDL supports something like this (I've
been using GLUT until now, and it doesn't seem to). I can create
a SDL_Surface, but I don't see a way to initialize this for openGL
drawing or set it as the current buffer to draw to. Thanks.
