portable library for OpenGL, window and input (development files)

 GLFW is a free, Open Source, framework for OpenGL application
 development. In short, it is a single library providing a powerful, portable
 API for otherwise operating system specific tasks such as opening an OpenGL
 window, and reading keyboard, time, mouse and joystick input.
 .
 It also provides functions accessing OpenGL extensions, creating and
 synchronizing threads and reading textures from files.
 .
 This package provides the header files and static libraries.
