Author: Eric Anholt <[email protected]> Date: Tue May 31 15:33:36 2011 -0700 intel: Use rb->Data and rb->RowStride to handle spans Y flipping. This is already pointing at 0 or Height - 1 and with an appropriate pitch, so no need to recompute those values per customization of the spans code. Cuts 3 out of 21kb of the compiled size.
