[Haskell] new SOE release with performance improvement

Thanks to the help from Peter Verswyvelen, a new SOE version is available at http://www.haskell.org/soe, under the name SOE-20071003.zip. This update makes better handling of events and buffer swap, and results in less CPU usage and smoother animation. The performance improvement may be quite apparent on some systems, in particular, those with software GL emulation rather than accelerated hardware. So if you are having performance issues running current SOE, I suggest you it a try. It has been tested on Windows, Linux, and OS X. PS: there's no change to GLFW since previous release, so if you have already installed GLFW, you don't need to re-install it. Regards, Paul Liu -- Yale Haskell Group http://www.haskell.org/yale
