Is it safe to check input and render in seperate threads? If I disable GLFW\_AUTO\_POLL\_EVENTS and only call Input related functions (glfwPollEvents, glfwGetKey, etc) in a thread other than the one calling Rendering functions, is that thread safe?

If this is OK, would I need to call glfwInit() in each thread or just the first one that I create?

BTW, Glad to find a recently updated crossplatform OpenGL library! Good job!
