@subsection keyboard_layout Keyboard layout
The human-readable name of the current keyboard layout is returned by @ref
glfwGetKeyboardLayoutName.
If you wish to be notified when the keyboard layout changes, set a keyboard
layout callback.
@code
glfwSetKeyboardLayoutCallback(keyboard_layout_callback);
@endcode
The callback is called when the new layout takes effect for the application,

@code
void keyboard_layout_callback(void)
{
update_keyboard_layout_name(glfwGetKeyboardLayoutName());
}
