-Name: The OpenGL Extension Wrangler Library
-URL: http://glew.sourceforge.net
-License File: LICENSE.txt
-
-This is Chrome's local copy of the GLEW library, which is currently
-used to interface to OpenGL and extensions to implement the WebGL
-specification.
-
-Compared to the original distribution:
-
-  - GLEW was changed to dynamically look up the OpenGL 1.1 entry
-    points in addition to those for later OpenGL versions and
-    extensions. This was necessary to be able to stop linking directly
-    against libGL.so on Linux due to http://crbug.com/16800 .
-
-  - The implementation of NSGLGetProcAddress has been changed to use
-    the standard dlfcn.h functions rather than the deprecated
-    mach-o/dyld.h ones.
-
-  - A GLEW_NO_GLU #define was added to prevent including GL/glu.h.
-
-  - A glxewContextInitWithDisplay(Display*) was added and exposed in
-    glxew.h in order to allow the GLX 1.3 entry points to be used to
-    create the first drawable.
-
-  - Fixed the order of #include guards around
-    _glewInit_GLX_VERSION_1_1 in glew.c when GLEW_MX is defined.
-
-  - For the case where GLEW_MX is not defined, added a wglewInit() and
-    support for dynamically looking up even the core WGL entry points.

-LICENSE.txt from that distribution has been preserved here.
