  8.  * EMSCRIPTEN GLFW 2.x-3.x emulation.
    9. 

  9.  * It tries to emulate the behavior described in
    10. 

  10.  * http://www.glfw.org/docs/latest/
    11. 

  11.  *
    12. 

  12.  * This also implements parts of GLFW 2.x on top of GLFW 3.x.
    13. 

  13.  *
    14. 

  14.  * What it does:
    15. 

  15.  * - Creates a GL context.
    16. 

  16.  * - Manage keyboard and mouse events.
    17. 

  17.  * - GL Extensions support.
    18. 

  18.  *
    19. 

  19.  * What it does not but should probably do:
    20. 

  20.  * - Transmit events when glfwPollEvents, glfwWaitEvents or glfwSwapBuffers is
    21. 

  21.  *    called. Events callbacks are called as soon as event are received.
    22. 

  22.  * - Input modes.
    23. 

  23.  * - Gamma ramps.
    24. 

  24.  * - Video modes.
    25. 

  25.  * - Monitors.
    26. 

  26.  * - Clipboard (not possible from javascript?).
    27. 

  27.  * - Multiple windows.
    28. 

  28.  * - Error codes && messages through callback.
    29. 

  29.  * - Thread emulation. (removed in GLFW3).
    30. 

  30.  * - Image/Texture I/O support (removed in GLFW 3).
    31. 

  31.  *
    32. 

  32.  * Authors:
    33. 

  33.  * - Jari Vetoniemi <mailroxas@gmail.com>
