Change all producer of libass images to packing the bitmaps into a single larger bitmap directly when they're output. This is supposed to help working towards refcounted sub bitmaps. This will reduce performance for VOs like vo_xv, but not for vo_opengl. vo_opengl simply will pick up the pre-packed sub bitmaps, and skip packing them again. vo_xv will copy and pack the sub bitmaps unnecessarily - but if we want sub bitmap refcounting, they'd have to be copied anyway. The packing code cannot be removed yet from vo_opengl, because there are certain corner cases that still produce unpackad other sub bitmaps. Actual refcounting will also require more work.
