Subject: [PATCH] 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!
