Subject: Fix expose of to-square with grid off
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=a944d7681f5c000551235be7c2257a31e27b75e9

Fix expose of to-square with grid off

The code relied on drawHighlight to request an expose evet for the entire
square, but when lineGap = 0, drawHighlight is a no-op.
