Fixes from Brian to help migrate to render buffer DD interfaces. Also fix bug in the viewport function that was using the viewport size to resize the buffer, when it should have been using the window size. Fix bug in write_rgb_span_32 where the incoming pixel data parameter was coded as a [][4] instead of [][3]. Now all the demos work correctly except singlebuffer.
