From 295fb9fd83512432404cd701c8b09bae4e627e20 Mon Sep 17 00:00:00 2001 From: Simon Tatham Date: Sun, 18 Sep 2011 07:43:18 +0000 Subject: [PATCH] When we run out of background colours for chains and wrap back to the beginning, we should wrap back to COL_B0+1 rather than COL_B0 itself, so as not to reuse white. White should be special, and always indicate a properly numbered square.
