2008-07-08 Minor fixes.
2008-07-07 Added new convenience methods for Game implementations.
2008-07-03 Lots of reworking. Completed support for game history, including Turn class. Changed Game API around quite a bit.
2008-05-29 Finally fixed the slow animation performance of board games; all it took was changing the board's z index from 1 to 0, somehow. Games working well now.
2008-03-12 Fixed the conversion of window to layer coordinates. The old way didn't work in HiDPI. Thanks to Quincey Morriss and Nathan Vander Wilt for figuring this out.
2008-03-11 Added support for clicking the board to place new pieces. Go and Tic-Tac-Toe now use this.
2008-03-07 Initial check-in into Mercurial. Branched from 1.0 release of Apple's sample code. No longer requires garbage collection. Fixed some memory leaks of CG objects. Fixed a bug when advancing to the 8th row in the Checkers game.
