// This needs to be used along with a Renderer (e.g. OpenGL2, OpenGL3, Vulkan..)
// Issues:
// [ ] Platform: CTRL+Tab can't be read.
// [ ] Platform: Keys are all generally very broken. Best using [event keycode] and not [event characters]..
// [ ] Platform: Mouse cursor shapes are not supported (see end of https://github.com/glfw/glfw/issues/427)
// [ ] Test with another renderer back-end than OpenGL2. e.g. OpenGL3.
