/*
* EMSCRIPTEN GLFW 2.x-3.x emulation.
* It tries to emulate the behavior described in
* http://www.glfw.org/docs/latest/
*
* This also implements parts of GLFW 2.x on top of GLFW 3.x.
*
* What it does:
* - Creates a GL context.
* - Manage keyboard and mouse events.
* - GL Extensions support.
*
* What it does not but should probably do:
* - Transmit events when glfwPollEvents, glfwWaitEvents or glfwSwapBuffers is
* called. Events callbacks are called as soon as event are received.
* - Input modes.
* - Gamma ramps.
* - Video modes.
* - Monitors.
* - Clipboard (not possible from javascript?).
* - Multiple windows.
* - Error codes && messages through callback.
* - Thread emulation. (removed in GLFW3).
* - Image/Texture I/O support (removed in GLFW 3).
