Subject: [PATCH] fix: use pixel values for diagonal AC background scroll

Percentage-based background-position translates to unequal pixel offsets
(268px X vs 768px Y on a 1280x768 viewport), making the movement appear
mostly vertical. Equal pixel values (1012px, 1012px) give a true 45-degree
diagonal. X loops seamlessly at the tile width boundary.
