Subject: Fix redundant redrawing in Pegs. Apparently it has always redrawn
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=4f81608c40cdecec7448d97f4bbf7f01b524b963;p=sgt-puzzles.git

Fix redundant redrawing in Pegs. Apparently it has always redrawn
every single peg and hole on the board, every time it did any kind of
redraw at all, because I forgot to update the array in the drawstate
indicating the last-drawn state of each position. And nobody's noticed
until now!
