Depending on who and when you ask, the freeglut license has been called "the MIT license" or the "XFree86 license". I am taking the (as of early 2005) official freeglut web site as the final word on this and direct the reader to the MIT license as defined on SourceForge. freeglut has had adequate time to correct that if it was in error. Other than the added copyrights, this is retained by OpenGLUT and OpenGLEAN. Here is the "generic form" of the MIT license that we use:
Copyright (c) <year> <copyright holders>

Except for a bit of code lifted from X, and the font data, all freeglut code is considered to be subject to this license, with suitable copyrights according to the author. OpenGLUT embraced this license for its as does OpenGLEAN. So other than the X material, all code is licensed as above.
The Adobe fonts (Helvetica and TimesRoman) were extracted from an X server and bear this copyright and license:
