description = """
The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source
C/C++ extension loading library. GLEW provides efficient run-time mechanisms
for determining which OpenGL extensions are supported on the target platform.

GLEW comes with three different backends that unfortunately must be selected
by loading another version of GLEW.
* GLX: The default backend on Linux, for on-screen rendering or rendering using
  VirtualGL
* EGL: Technically capable of both on-screen and off-screen rendering
* OSMESA: Backend for off-screen rendering only.
