Help Wanted page updated.

The Help Wanted page has been updated with several areas you could help develop. They range from implementation specific topics (e.g. Mac OS X support) to advanced OpenGL techniques (HDR, GLSL programs). OpenGL tutorials are especially welcome now that we are nearing the first stable release.

If you think you can help with any of these, please add a comment here, or make a post at the development forums. Thanks!
