Packed Cell Cellmate Bypass

Gallery / Serpentine Layout

The same non-consumer bypass as manual_rl_row_nonconsumer_bypass, but the intervening section is packed into the same grid cell as the target rather than given its own cell. The bypass must still loop around the cell-mate's box instead of cutting straight through it (issue #1228).
