+ *  If `mode` is `GLFW_CURSOR_MODE`, the value must be one of the supported input

+ *  * `GLFW_CURSOR_NORMAL` makes the cursor visible and behaving normally.
+ *  * `GLFW_CURSOR_HIDDEN` makes the cursor invisible when it is over the client

+ *  If `mode` is `GLFW_STICKY_KEYS`, the value must be either `GL_TRUE` to
+ *  enable sticky keys, or `GL_FALSE` to disable it.  If sticky keys are

+ *  before the call.

+ *  If `mode` is `GLFW_STICKY_MOUSE_BUTTONS`, the value must be either `GL_TRUE`
