- Found testing core_input_gamepad. The last axis was not drawn.
- GLFW_GAMEPAD_AXIS_LAST is defined to the last axis which is 5

After some investigation, I came to the conclusion it's impossible to get a solution that works for all situations.

Just choose a solution that fits me needs for now and let the user manage the canvas on their webs (hopefully not requiring ToggleFullscreen() call).

Also removed several useless related callbacks.
