Bindings to GLFW (http://www.glfw.org/), an open source, multi-platform
library for creating windows with OpenGL contexts and managing input and
events.
GLFW-b depends on bindings-GLFW
(http://hackage.haskell.org/package/bindings-GLFW), which, as of the time
of this writing, binds to GLFW 3.3.0, released 2019-04-15
(http://www.glfw.org/Version-3.3.0-released.html
http://www.glfw.org/changelog.html).
If you've used GLFW < 3 before, you should read the transition guide
(http://www.glfw.org/docs/3.0/moving.html).
