Vulkan surface creation error

See original GitHub issue

using glfw.create_window_surface I get an error:

ctypes.ArgumentError: argument 1: <class ‘TypeError’>: wrong type

argument 1 is the vulkan instance and mine was created as it should : <cdata 'struct VkInstance_T *' 0x0000022EF5F83520>

I have just released pyGLFW1.12.0 which contains some utilities for working with CFFI based Vulkan wrappers. You can now do the following:

surface_ptr = ffi.new('VkSurfaceKHR[1]')
glfw.create_window_surface(instance, window, None, surface_ptr)
surface = surface_ptr[0]

and pyGLFW will automatically convert the CFFI pointers to ctypes pointers.
