Subject: [PATCH] Swap vertical/horizontal variables in row/column calculation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently has no impact as all code-sizes are square, but if support for rectangular DataMatrix would be added, then this would have been an issue.
(I might try to add that support, but I don't know Go 🙂)
